Description

Thoracoscope disposable hand perspiration syndrome puncture sheath pipe

Technical Field

The utility model relates to the technical field of medical equipment, concretely relates to thoracoscope is disposable hand sweat puncture sheath pipe.

Background

Bilateral sympathetic nerve chain cutting under thoracoscopy is an effective method for treating moderate and severe primary hand perspiration disease. The surgical methods have been improved over 3-hole, 2-hole thoracoscopes, and single-hole techniques, surgical modalities, and medical instruments that have been commonly used to date. The currently clinically and generally adopted method is a 5mm thoracoscope single-hole method or a double-hole method. The single-hole surgical procedure is as follows: the operator only needs to do a 8mm incision of controlling the size between the 3 rd rib of line before the armpit of patient armpit portion, puts into 5mm thoracoscope, then puts into 5mm electricity and congeals the hook in same downthehole, under thoracoscope guides, fixes a position sympathetic nerve chain, and the sympathetic nerve chain is cut off in the 3 rd or 4 th back rib surface electricity congeals, just can reach the purpose of curing hand sweat disease, and the success rate is more than 99%. The double-hole method is to make a 5mm incision on the 3 rd intercostal axillary anterior line for placing a 5mm electrocoagulation hook, and to make a 5mm incision on the 4 th or 5 th intercostal axillary midline for placing a 5mm thoracoscope. The single-hole method reduces an incision compared to the double-hole method, and is more acceptable to patients for such a surgery with cosmetic properties. Therefore, the single-hole method of the 5mm thoracoscope for treating the hand perspiration disease is the conventional method at present. In the operation process, a surgeon firstly needs to use a thoracoscope puncture outfit to puncture the chest wall to establish an operation channel, and then can put a thoracoscope and an electrocoagulation hook through the channel to complete the follow-up operation. The thoracoscope puncture outfit mainly comprises a puncture sheath and a puncture needle, an operator firstly sleeves the puncture sheath on the puncture needle, then uses a certain force to act on the tail part of the puncture outfit, punctures the chest wall by the sharp tip of the puncture needle to enable the whole puncture outfit to enter the thoracic cavity, and then pulls out the puncture needle to leave the puncture sheath to form an operation channel. In the single-hole method, when the electric coagulation hook is placed in the same operation channel by virtue of the thoracoscope, the thoracoscope and the electric coagulation hook are easy to interfere with each other, and the accuracy and the safety of operation are influenced. And sometimes an artificial pneumothorax is required, i.e. the puncture device must have a sealing function. Therefore, it is desirable to have a puncture device with a movable passage and a gas-sealing function.

The utility model patent CN202637059U discloses a take flexible thoracoscope puncture ware of many handle holes contains puncture ware sheath pipe and puncture ware core awl, and wherein, puncture ware sheath pipe contains sleeve pipe, body and injection gas pipeline, and wherein, the sleeve pipe outsourcing is outside the body, and injection gas pipeline inlays on the sleeve pipe, and puncture ware core awl passes the body nestification on puncture ware sheath pipe. The utility model discloses a reduce the operation incision for the thoracoscope operation, reduce the wound and provide support to make the haplopore local anesthesia thoracoscope operation possible. However, the utility model discloses a relative motion range of body is limited, leads to among the thoracoscope operation process motion of thoracoscope and electricity congeals the hook to receive the restriction, operates inconveniently, and inserts the thorax in-process at the puncture ware, and the core awl readily releasable that is located the front end, and the resistance increases, hinders the puncture of puncture ware.
