Description

Technical Field

[0001] The invention relates to a medical device, in particular to a ligation forceps with a bent and detachable forceps head. Background Art

[0002] With the rapid development of concepts such as precision medicine, rapid recovery, and minimally invasive surgery, laparoscopic surgery has partially or completely replaced traditional open surgery in many fields. After nearly 20 years of continuous progress, laparoscopic surgery has quickly become a "unique" surgical operation with its advantages of less trauma, less pain, fewer complications, better appearance, and shorter hospital stay. The development of laparoscopic surgery is inseparable from the innovation and progress of surgical instruments. Among them, the laparoscopic automatic ligator is an indispensable "weapon" in laparoscopic surgery. The automatic ligators currently used in clinical practice are mainly Hem-o-lok produced by Teleflex in the United States. There are also automatic ligators produced by domestic manufacturers, and their structures, functions, and usage are very similar. Ligation clips are mainly used to ligate blood vessels or tissues during surgery, and are widely used in laparoscopic, thoracoscopy, pelvicoscopy and other surgeries. Although the automatic ligator is easy to use and has reliable effects, its ligating forceps are straight and cannot be bent. For some angled tissues or blood vessels, the automatic ligator cannot perform vertical ligation or the ligating clip lock cannot be clearly displayed due to the obstruction of the ligating forceps' field of view, which brings inconvenience and safety hazards to the operation. Summary of the invention

[0003] In order to solve the above technical problems, the present invention provides a ligation forceps with a bent and detachable forceps head, comprising a forceps handle, a forceps tube, a rotating wheel, a detachable forceps head and an inner rod, the forceps handle comprising a left forceps handle and a right forceps handle, the left forceps handle being connected to the right forceps handle by a screw, and the forceps handle being arranged at one end of the forceps tube, the rotating wheel being arranged on the forceps tube, the other end of the forceps tube being arranged with a forceps tube connecting portion connected with the detachable forceps head, the inner rod being arranged in the forceps tube, the end of the inner rod close to the forceps handle being arranged with a push rod, and the other end of the inner rod being arranged with a The second magnet is fixedly connected to the clamp tube through a sealing sleeve, the detachable clamp head comprises an inner clamp seat, an outer clamp seat, a left clamp head and a right clamp head, the left clamp head and the right clamp head are connected to the outer clamp seat through an axle pin, and the outer clamp seat is fixedly arranged on the detachable clamp head, a slide pin is fixedly arranged on the inner clamp seat, and the outer clamp seat, the left clamp head and the right clamp head are connected to the inner clamp seat through the slide pin, a first magnet connected to the second magnet is arranged at one end of the inner clamp seat, and a clamp head connecting plate is arranged at the end of the detachable clamp head connected to the clamp tube.

[0004] Furthermore, a push rod pin is provided on the push rod, and the left clamp handle is connected to the push rod pin.

[0005] Furthermore, a fixing sleeve is fixedly arranged on the inner rod, a compression spring is arranged between the fixing sleeve and the sealing sleeve, one end of the compression spring close to the fixing sleeve abuts against the surface of the fixing sleeve, and one end of the compression spring away from the fixing sleeve abuts against the sealing sleeve.

[0006] Furthermore, the detachable pliers head can be bent at an angle of 0°-90°.

[0007] The advantage of the present invention is that the forceps head part can be bent, which solves the problem that some angled tissues or blood vessels cannot be ligated during surgery. The present invention enables the operator to ligate blood vessels more flexibly during surgery. The present invention is simple to operate, and the operator can easily use the present invention, which makes the patient safer during surgery. BRIEF DESCRIPTION OF THE DRAWINGS
