Abstract
This utility model relates to disposable sleeve perforator, and it comprises puncture inner core, fixed sleeving and location and fixed part, it is characterized in that the lateral surface of fixed sleeving has male thread; Location and fixed part comprise the annular flange flange at top pipe and the lower nozzle place at top pipe, and the medial surface of described top pipe has box thread, and described annular flange flange circumferentially has three flexible sucker, and described three flexible sucker are by this circumference trisection; To locate by the male thread on the lateral surface of location and the box thread on the medial surface of the top pipe of fixed part and fixed sleeving and fixed part is connected to the outside of fixed sleeving.Disposable sleeve perforator of the present invention can be located accurately and be guaranteed puncture accurately, significantly reduces the movement of this sleeve puncture outfit in operation process and the friction to wound simultaneously, reduces the misery of operation and contributes to the recovery of postoperative wound.
Description
Technical field
This utility model relates to medical instruments field technology, particularly a kind of sleeve puncture outfit of disposable celiac mirror.
Background technology
Be that the Minimally Invasive Surgery of representative developed rapidly in recent years with peritoneoscope, in developed country, its amount for surgical has exceeded traditional operation.Minor operation, little wound are the accreditation that the minimally-invasive treatment technology of feature progressively obtains numerous doctors.Sleeve puncture outfit is for setting up operation path, observing the indispensable apparatus of passage in laparoscopic surgery.The sleeve puncture outfit of prior art, adopt fixed sleeving and the form of inner core combination of puncturing, thrust the degree of depth entirely with operating the experience of doctor and feeling to carry out, often because grasp is bad injure internal organs in abdomen, form malpraxis or accident, cause unnecessary misery to patient.In addition, can not be fully fixing owing to thrusting rear sleeve, cause the slight movement of sleeve pipe in operation process and to rub the misery the recovery affecting postoperative wound that also can add heavy patient with wound.
Summary of the invention
The purpose of this utility model is, overcome the deficiencies in the prior art part, a kind of disposable celiac mirror sleeve puncture outfit is provided, guarantee that puncture accurately to locate accurately, lay a good foundation for carrying out laparoscopic surgery, this sleeve puncture outfit firmly can be fixed on the position of wound after thrusting simultaneously, significantly reduces the movement of this sleeve puncture outfit in operation process and the friction to wound, reduces the misery of operation and contributes to the recovery of postoperative wound.
Disposable celiac mirror sleeve puncture outfit described in the utility model comprises puncture inner core, fixed sleeving and location and fixed part, it is characterized in that the lateral surface of fixed sleeving has male thread; Location and fixed part comprise the annular flange flange at top pipe and the lower nozzle place at top pipe, and the medial surface of described top pipe has box thread, and described annular flange flange circumferentially has three flexible sucker, and described three flexible sucker are by this circumference trisection; To locate by the male thread on the lateral surface of location and the box thread on the medial surface of the top pipe of fixed part and fixed sleeving and fixed part is connected to the outside of fixed sleeving.Described fixed sleeving and puncture inner core are main components of the present utility model, are inserted by puncture inner core to be used as to pierce through skin and flesh in fixed sleeving, and successfully rear extraction of puncture is punctured inner core, namely operates by sleeve pipe importing operating theater instruments.Because location and fixed part are threadedly attached to the outside of fixed sleeving, therefore logical and be easy to adjustment and thrust the degree of depth by rotating location and fixed part.After determining to thrust the degree of depth and complete and thrust, by location and fixed part annular flange flange on three flexible sucker be adsorbed on the skin around entry of stab wound, form the firm triangle of equilateral triangle to fix, thus effectively prevent in operation process and cause the slight movement of sleeve puncture outfit and the friction to wound.
Use disposable celiac mirror sleeve puncture outfit described in the utility model, preoperative through operator estimate or measure thrust the degree of depth, localizer is located by the degree of depth according to thrusting on fixed sleeving, can implement to thrust, fixed by location and the firm triangle that three flexible sucker in the annular flange flange of fixed part can realize sleeve puncture outfit after thrusting, peritoneoscope and corresponding operating theater instruments can be used subsequently to implement operation.
Accompanying drawing illustrates:
Accompanying drawing is the structural representation of disposable celiac mirror sleeve puncture outfit described in the utility model.
Detailed description of the invention:
Referring now to accompanying drawing, be described as follows: disposable celiac mirror sleeve puncture outfit sleeve puncture outfit described in the utility model comprises puncture inner core 1, fixed sleeving 2 and location and fixed part 3, it is characterized in that the lateral surface of fixed sleeving 2 has male thread in conjunction with the embodiments; Location and fixed part 3 comprise the annular flange flange 3-2 at top pipe 3-1 and the lower nozzle place at top pipe, the medial surface of described top pipe has box thread, described annular flange flange 3-2 circumferentially has three flexible sucker 3-3, and described three flexible sucker 3-3 are by this circumference trisection; To locate by the male thread on the lateral surface of location and the box thread on the medial surface of the top pipe 3-1 of fixed part 3 and fixed sleeving 2 and fixed part 3 is connected to the outside of fixed sleeving 2.Rotate location and fixed part 3, can make to locate and move up and down along the lateral surface of fixed sleeving 2 with fixed part 3, also namely make the change up and down of the position of annular flange flange 3-2, thus can adjust sleeve puncture outfit thrust the degree of depth.After sleeve puncture outfit is thrust, location reaches skin surface with the annular flange flange 3-2 of fixed part 3, by circumferentially three flexible sucker absorption at described annular flange flange 3-2 firmly being fixed on a skin surface and by sleeve puncture outfit, thus in operation process, prevent the slight movement of sleeve puncture outfit and the friction to wound.
Use disposable celiac mirror sleeve puncture outfit described in the utility model, preoperative through operator estimate or measure thrust the degree of depth, localizer is located by the degree of depth according to thrusting on fixed sleeving, can implement to thrust, fixed by location and the firm triangle that three flexible sucker in the annular flange flange of fixed part can realize sleeve puncture outfit after thrusting, peritoneoscope and corresponding operating theater instruments can be used subsequently to implement operation.
