Embodiment Construction

[0028] Referring to the accompanying drawings, the present invention will be further described in detail with specific embodiments.

[0029] Such as Figure 1-9 As shown, the bipolar electric energy forceps head for minimally invasive surgical instruments disclosed by the present invention includes a first forceps leaf 1, a second forceps leaf 2, a spacer 3, a supporting plate 4, a forceps shaft 5, a sleeve 6, a wire 7. It consists of bipolar connecting rod 8, bipolar pull seat 9, end support 10, wire guide wheel 11 and steel wire 12. The end support 10 is used for fixed connection with the instrument shaft of the minimally invasive surgical instrument.

[0030] The first clamping leaf 1 and the second clamping leaf 2 are positive and negative dual electrodes, and the fixed position of the clamping shaft 5 is insulated by fastening the support piece 4 and the spacer 3, and the positive and negative electrodes of the clamping pages are insulated and isolated from the rest of t...

Abstract

The invention relates to a bipolar electric energy forceps head for a minimally invasive surgical instrument, and solves the technical problems that an insulation isolation structure of two forceps blades of an existing electrode forceps head surgical instrument is poor in insulation effect, and the opening and closing actions of the two forceps blades adopt a spring type opening and closing clamping structure which causes difference to the opening angles of the forceps blades. The bipolar electric energy forceps head comprises forceps blades, isolation sheets, supporting sheets, a forceps shaft, a wire, bipolar connecting rods, a bipolar pull seat, a tail end support and a steel wire, wherein the two isolation sheets are fixedly connected with the two forceps blades correspondingly. the two supporting sheets are fixedly connected with the first isolation sheet and the second isolation sheet correspondingly; the forceps shaft penetrates through the two isolation sheets and the two supporting sheets; the upper end and the lower end of the first bipolar connecting rod are hinged to one end of the first isolation sheet and one end of the bipolar pull seat respectively, the upper end and the lower end of the second bipolar connecting rod are hinged to the other end of the second isolation sheet and the other end of the bipolar pull seat respectively, and a wire guide wheel is fixedly connected to the middle of the forceps shaft; and the end of the forceps shaft is located in a guide groove of the tail end support. The bipolar electric energy forceps head is widely applied to the technical field of minimally invasive surgery robots.

Description

technical field [0001] The invention relates to the technical field of minimally invasive surgical robots, in particular to a bipolar electric energy forceps head for minimally invasive surgical instruments. Background technique [0002] Reference application publication number CN109091237A, Chinese invention patent application titled Minimally Invasive Surgical Instrument Auxiliary System, minimally invasive surgery represented by laparoscopy is known as one of the important contributions of medical science to human civilization in the 20th century, minimally invasive surgical operations It means that the doctor uses the slender surgical tools to penetrate into the body through tiny incisions on the surface of the human body for surgical operations. Compared with traditional open surgery, it has the advantages of small surgical incision, less bleeding, small postoperative scar, and quick recovery time, which greatly reduces the pain suffered by patients; therefore, minimall...
