Patent number: 11478294Abstract: A medical instrument comprising a device for activating or deactivating a function of the instrument. The device comprises first and second parts, which are each movable into an operative position relative to the other part to activate or deactivate a function of the instrument. A second control element for moving the second part into the operative position provides a control portion and comprises, for moving the first part into the operative position, a first control element which provides an additional control portion. The first control element can be moved in an opposite direction the direction from the second control element. Accordingly, the function is activated by moving a control element in a distal direction, and by moving another control element in a proximal direction. A deflection of force by one actuating element for actuating the first part or the second part in the opposite direction is not necessary.Type: GrantFiled: August 28, 2019Date of Patent: October 25, 2022Assignee: ERBE ELEKTROMEDIZIN GMBHInventors: Markus Paesch, Volker Buntrock, David Loeser, Stefanie Schmidt

Publication number: 20220331002Abstract: A knife cartridge for use in a surgical instrument. The knife cartridge includes a blade that can be operated by a second operating element. The blade is held in a blade housing that can be transferred from a first locking position (passive position) into a second locking position (active position) by a first operating element. In the passive position the blade housing is completely located inside the cartridge housing and the blade is locked therein. In the active position the blade housing projects out of the cartridge housing. Only in the active position a locking between the blade housing and blade can be released, whereby also only then a driving connection is established between the second operating element and the blade.Type: ApplicationFiled: April 7, 2022Publication date: October 20, 2022Applicant: Erbe Elektromedizin GmbHInventor: Felix Bob

Publication number: 20220273278Abstract: A retrieve device for retrieving tissue having a retrieve bag that is at least in part a hydrophilic water permeable filter diaphragm. The filter diaphragm may have a pore width that allows for blocking passage of pathogen cells or other pathogen material. The pores width may also be large enough to allow water to exit out of the retrieve bag. Liquid in the retrieve bag can be expelled through the filter diaphragm and thus does not contribute the volume of the retrieve bag.Type: ApplicationFiled: February 15, 2022Publication date: September 1, 2022Applicant: Erbe Elektromedizin GmbHInventors: Uwe Schnitzler, Markus Enderle

Patent number: 11426187Abstract: The forceps instrument includes a central pull-push member formed by transmission and actuating elements. The central push-pull member opens and closes the branches, and also acts as a tissue abutment that is variable based on the degree of closure of the branches. The variable tissue abutment may be configured as a slider element and is adjustable proportionally to the opening angle of the branches. When grasped, the vessels are brought proximally. The tissue abutment acts as a spacer between the hinge region and the grasped material. While the branches are being closed, the vessel is held stationary and compressed. During compression, expansion of the vessel occurs axially in distal and proximal directions. Due to the receding of the variable tissue abutment during the closing operation, room is created for the grasped material to escape. Tissue accumulations can thus be restricted and overstressing of the tissue can be counteracted.Type: GrantFiled: June 7, 2019Date of Patent: August 30, 2022Assignee: Erbe Elektromedizin GmbHInventors: Achim Brodbeck, Matthias Voigtlaender, Bernhard Nold, Tim Closs

Patent number: 11234724Abstract: An instrument including an actuation gear mechanism that provides two functions of a tool. The actuation gear mechanism comprises a cam mechanism and a gear segment mechanism. The circumference of the cam disk of the cam mechanism—in a first section (?1)—is a spiral curve for generating a stroke for closing the forceps tool, while the circumference of the cam disk—in a second, adjoining, angular range (?2)—is circular. When the cam disk with the circular curved line biases the spring means, no further movement takes place on the output of the cam mechanism. Preferably, two congruent cam disks are provided, whereby these—together with the driving gear and the segment gear, as well as the shaft—form a one-piece plastic injection-molded part. The installation space between the cam disks can be utilized for a slide with a gear rack for shifting the knife.Type: GrantFiled: July 6, 2018Date of Patent: February 1, 2022Assignee: Erbe Elektromedizin GmbHInventors: Udo Kirstgen, Volker Buntrock

Patent number: 11207121Abstract: A device (10) for tissue coagulation, in particular for fusion, encompasses an electric source (18), which is connected or which can be connected to electrodes (12, 13) for influencing biological tissue (11) with current. A control unit (22) controls the source (18) during phases I and II of the tissue fusion. These phases I and II correspond to operating phases I, II and III of the device (10). During operating phase I, a monitoring unit (23) determines the energy E1, which is applied into the tissue (11). In the subsequent operating phases II and III, the control unit (22) controls the source (18) by means of the determined energy E1. Such a device turns out to be particularly reliable and to be robust in use.Type: GrantFiled: May 4, 2018Date of Patent: December 28, 2021Assignee: Erbe Elektromedizin GmbHInventors: Heiko Schall, Daniel Schaeller

Patent number: 11197711Abstract: A tissue fusion instrument having electrodes that are only connected in a punctiform manner to their electrode carrier such that they are electrically conducting and thus, heat-conducting. As a result, heat transfer from the electrode to the respective electrode carrier is restricted. This, on one hand, benefits the desired surgical outcome and, on the other hand, prevents parasitic heating of the surgical instrument and concomitant damage to surrounding tissue.Type: GrantFiled: April 9, 2019Date of Patent: December 14, 2021Assignee: ERBE ELEKTROMEDIZIN GMBHInventors: Klaus Fischer, Achim Brodbeck, Daniel Schaeller

Publication number: 20210322087Abstract: An operation device for operating a tool of a surgical instrument. The operation device has an operation element that is pivotably supported between an initial position and a working position. The operation element is movably coupled with the tool by means of a coupling device comprising a coupling link or consisting of a coupling link. The coupling link is elastically deformable and effectuates a resetting torque due to the elastic deformation in case the operation element is deflected out of the initial position, wherein the resetting torque urges the operation element back in the initial position.Type: ApplicationFiled: April 7, 2021Publication date: October 21, 2021Applicant: Erbe Elektromedizin GmbHInventor: Felix Bob
