Surgical department shearing device used for endoscopy surgery

Abstract

The invention relates to a surgical department shearing device used for endoscopy surgery, comprising a holding part, a connecting rod structure part and a shearing part, wherein the holding part comprises a force applying part, a fixedly holding part and a knob linkage rod, and the knob linkage rod is respectively connected with the force applying part and the fixedly holding part; the connecting rod structure part is arranged on the front end of the force applying part and the fixedly holding part and comprises a fixed connecting rod, a drive rod and a groove on the drive rod; the shearing part is jointed on the front end of the connecting rod structure part and comprises a left and right sheetbody connecting rod and a left and right sheetbody for shearing or stripping a subject matter.The invention has favorable stability during operation, has small possibility of shaking and can accurately shear the subject matter.

Description

technical field [0001] The invention relates to a surgical cutting device for endoscopic surgery, which can be applied to soft tissues, including internal organs in the abdominal cavity and thoracic cavity, and can separate and cut tissues during endoscopic surgery. Background technique [0002] Existing surgical endoscopic surgical scissors structure, such as figure 1 As shown, it includes a finger grip 101 for applying force, a fixed finger grip 102, which supports the finger grip 101 when applying force, and the upper end of the fixed finger grip 102 has a gear-shaped structure 103, which drives a cavity when applying force. The wheel shaft in the chamber 112 rotates, and the chamber 112 is used as a force output conversion space during force application. The wheel shaft 104 and the fixed rod 105 connected in the chamber 112 are used as a force output member when the force is applied. The front end 113 of the fixed rod has a groove 106 , the groove 106 is provided with a...

AI Technical Summary

Problems solved by technology

[0005] The existing technology is an upright grip, applying force to the finger grip 101, passing through the wheel shaft 104 and the fixed rod 105 of the power output member in the chamber, passing through the gear 103, to the wheel shaft 104, and then driving the push and pull of the sleeve 107 to finally transmit to the At the place where the force is applied, the left and right two pieces 110 can complete the action of cutting the target object. Because the finger grip 101 at the point of application, the fixed finger grip 102, the sliding bolt 109 at the point of application, and the left and right two pieces 110 form a right angle, and the output force passes through the wheel shaft, shaft The sleeve cannot transmit the force directly to the point of force, making it difficult to control the force of the point of force, and it will cause damage to the organization due to inappropriate force

Furthermore, during operation, the main action is the force exerted by the thumb of the hand, and the rest of the fingers are used as fixation and auxiliary force. When the thumb exerts force, the rest of the fingers in the natural human movement will also exert force, which will cause the main body 100 to shake. , it is not easy to be stable, and it is not easy to perform shearing operations on smaller targets, resulting in less precise operations.

[0006] To sum up, at present, all the instruments used in endoscopic surgery adopt a force application method different from conventional surgical instruments, and the force is indirectly transmitted through related mechanisms, and it is difficult to control the force of the force point. This kind of surgical operation method is increasing. Reduced the difficulty of endoscopic surgery with technical requirements
