Hook assembly for hepatobiliary surgery

Abstract

The invention discloses a hook assembly for hepatobiliary surgery and relates to the technical field of the hepatobiliary surgery. The hook assembly comprises a fixing rod, wherein a front surface ofthe fixing rod is provided with a through hole, a back surface of an inner wall of the through hole is provided with a sliding groove, the sliding groove is internally in sliding connection with a sliding block, and a left side surface of the sliding block is clamped with a first threaded cylinder. The hook assembly is advantaged in that a surgical fixation bracket for the general surgery is utilized, through cooperation of a surgical hook body, a first threaded column, the sliding block, the sliding groove, a handle, the fixing rod and a first sliding rod, the left surgical hook body is driven by the first threaded column to move to the left, a surgical incision is dilated and fully exposed to the view field, an operator is allowed to perform an operation on the incision, the operator whostretches the incision during the operation is not replaced, accidental tearing of the incision caused by prolonged manual stretching of the incision by the operator is avoided, and thereby working difficulty of the operator is reduced.

Description

technical field [0001] The invention relates to the technical field of hepatobiliary surgery, in particular to a drag hook assembly for hepatobiliary surgery. Background technique [0002] Surgery is referred to as surgery, commonly known as surgery, which refers to the operation of surgical equipment or instruments to enter the human body or other biological tissues under the operation of surgeons or other professionals, to eliminate lesions, change structures or implant foreign objects by external force. process.

For those who come to pull the hook, due to being too careful and unable to move for a long time, the operator will soon get tired. Usually, another person will change th...

AI Technical Summary

Problems solved by technology

[0005] Aiming at the deficiencies of the prior art, the present invention provides a retractor assembly for hepatobiliary surgery, which solves the problem that the operator who uses the retractor in general operations will soon become fatigued due to being too careful and unable to move for a long time. It will also change people, which increases the workload of doctors, prolongs the operation time, and also increases the patient's pain time.
