Description

Length-variable laparoscope holding and extending device

Technical Field

The invention relates to the field of medical instruments, in particular to a length-variable laparoscope holding lengthening device.

Background

In laparoscopic surgery, the length of most laparoscopic operation instruments is close to that of a laparoscopic photography illumination system, due to the limited operation space, in the actual operation (especially in a single-port laparoscope or in transvaginal laparoscopic surgery), the position of the hand-held endoscope is coincided with the operation position of an operator, and the problem that the operation of the operator is hindered by the position of the hand-held endoscope exists. Therefore, there is a need for a laparoscopic extended device with a variable length that matches the conventional laparoscopic operating instruments.

Disclosure of Invention

The invention provides a length-variable laparoscope holding lengthening device aiming at the problem that the operation of an operator is hindered due to the limited operation space in the actual operation of a conventional laparoscope operation instrument, and effectively solves various existing problems. The designed length-variable laparoscope holding lengthening device is added with the length-variable lengthening device on the basis of not changing the original structure of the conventional laparoscope, the length and the angle of the lengthening device are adjusted according to the actual conditions in the operation, and the problem of poor operability under the condition that the actual size and the space angle are limited is effectively solved.

In order to achieve the purpose, the length-variable laparoscope holding lengthening device comprises a holding handle, a thin extension rod, a thick extension rod, a round-head screw rod and a fixing sleeve, wherein a first threaded hole is formed in the front end of the holding handle; one side of the thin extension rod, which is close to the mirror holding handle, is provided with a first thread; the first thread is matched with the first threaded hole; a concave slideway is arranged at the axial top of the thin extension rod;

one end of the thick extension rod is provided with a second thread, and the top of one side, far away from the second thread, of the thick extension rod is provided with a through hole; the through hole is matched with the round-head screw; the thin extension rod and the thick extension rod are fixed through the round-head screw;

the fixing sleeve is of a two-section structure, the upper section is provided with a lock catch, and the lower section is provided with a lock catch sleeve; the lock catch is matched with the lock catch sleeve; a second threaded hole is formed in the top of one side, close to the thick extension rod, of the upper section of the fixing sleeve; the second threaded hole is matched with the second thread.

Preferably, the length of the thin extension rod and the length of the thick extension rod are controlled by adjusting the position of the round-head screw rod on the concave slideway, so that the total endoscope holding length of the laparoscope in the operation is prolonged, and the optimal operation variability and flexibility are ensured.

The angle of the lens holding handle and the thin extension rod is adjusted through a first thread; the fixed sleeve and the thick extension rod adjust the angle through the second thread, so that a space is reserved for the operation of an operator on the basis of not changing the original operation standing position of the endoscope holding assistant, and the problems that the holding position of the endoscope holding assistant hinders the operation of the operator and an anesthesiologist from observing the conditions of a patient in the operation are effectively avoided.

Under the optimal mode, the fixed cover is inside to be equipped with embedded soft cover, embedded soft cover is detachable soft material, guarantees to match with conventional peritoneoscope grip handle.

Compared with the prior art, the invention has the following advantages and positive effects: the length-variable laparoscope holding lengthening device can adjust the length and the angle of the lengthening device according to the model of a conventional laparoscope holding handle, the standing position of nursing staff in an operation and other conditions, reserve a space for an operator to operate on the basis of not changing the operation standing position of an original mirror holding assistant, effectively avoid the problems that the holding position of the mirror holding assistant is not good so as to hinder the operator to operate and hinder an anaesthetist from observing the conditions of a patient in the operation, and greatly improve the efficiency and the operation safety of medical staff.

Specifically, the beneficial effects are as follows:

1. the length-variable laparoscope holding extension device is characterized in that the thin extension rod and the thick extension rod are fixed and adjusted in length through the round-head screw rod; the angle of the lens holding handle and the thin extension rod is adjusted through a first thread; the angle of the fixed sleeve and the thick extension rod is adjusted through a second thread. The length and the angle can be adjusted according to the self requirement, the original operation station of the endoscope holding assistant is not changed, a space is reserved for the operation of an operator, and the problems that the holding position of the endoscope holding assistant obstructs the operation of the operator and obstructs an anesthesiologist to observe the conditions of a patient in the operation are effectively avoided.

2. The length-variable laparoscope holding lengthening device is characterized in that the fixing sleeve is of a two-section structure, the upper section of the fixing sleeve is provided with a lock catch, and the lower section of the fixing sleeve is provided with a lock catch sleeve; the padlock is matched with the padlock sleeve. And an embedded soft sleeve is arranged in the fixed sleeve and is made of a detachable soft material. This design plays good fixed action on the one hand, and the padlock can be opened in a flexible way moreover, does not influence and uses repeatedly, increase of service life. On the other hand, the embedded soft sleeve can be replaced at any time according to requirements due to different models and different shapes of the laparoscope holding handles of different manufacturers, so that the laparoscope holding handles of different models are adapted.
