Description

Special snare device for hysteroscopy mirror operation

Technical Field

The utility model relates to a special snare device of hysteroscopy mirror operation belongs to medical articles for use technical field.

Background

Hysteroscopy is a very common operation mode in obstetrics and gynecology department, and along with the gradual improvement of health consciousness of people, more and more patients may find the problem of the uterine cavity through B-ultrasonic examination in gynecology department, thereby receiving the operation of hysteroscopy. Uterine cavity occupation is a clear surgical indication of hysteroscopic surgery, and comprises common diseases such as endometrial polyps, submucosal myomas of uterus and the like.

The current hysteroscopic surgical instruments commonly used comprise a hysteroscopic resectoscope and a hysteroscopic inspectoscope. Wherein the hysteroscope resectoscope tube sheath is relatively big in diameter (for example, the external diameter of the Olibbus resectoscope is 9 mm), and the cervical canal needs to be mechanically dilated by the uterine dilating rod before the operation, so that the cervical injury of partial patients, such as old women (cervical atrophy) and unmarried women, is relatively large. The general pipe diameter of hysteroscopy mirror is less (as wolf brand integrative palace chamber inspection mirror, the external diameter is 5 mm), and its main function is the inspection, generally does not do the electrotomy treatment, though there is the accessory that can stretch into the palace chamber, including biopsy forceps, nipper, miniature operation scissors etc. nevertheless can't carry out effectual excision to the thick big endometrial polyp of part pedicel portion to because of cervical dilatation is not enough, partly great tissue specimen can't conveniently take out.

Preferably, the tube sheath comprises a tube sheath head section and a tube sheath tail section, the rear end of the tube sheath head section is connected with the front end of the tube sheath tail section, the tube sheath head section is sleeved in the front end of the tube sheath head section, and the handheld operating handle is connected with the rear end of the tube sheath tail section; the head section of the tube sheath is a rigid structure with smooth surface and hard substance; the tail section of the tube sheath is an elastic part; when the elastic part is not compressed, the length of the inner core is consistent with that of the tube sheath; when the resilient portion is compressed, the inner core extends out of the sheath and forms a snare loop.

Preferably, the tail section of the sheath is formed by a spring structure with elasticity, such as metal or other materials.

The utility model is mainly used for resection of uterine cavity tissue and taking out of specimens in hysteroscopy operation; the main principle of the hysteroscopy scope is designed according to the operation channel and defects of the traditional hysteroscopy scope and a commonly used snare structure.

Compared with the prior art, the utility model discloses following beneficial effect has:

1. by using the middle ring sleeve of the utility model, part of endometrial polyp can be directly and conveniently cut off/drawn out;

2. can assist in exposing the surgical field;

3. the larger operation specimen can be taken out more conveniently.

Detailed Description

In order to make the present invention more comprehensible, preferred embodiments are described in detail below with reference to the accompanying drawings.

The utility model provides a special snare device of hysteroscopy mirror operation for polyp excision, myoma tractive etc. in the operation process of hysteroscopy, as shown in figure 1, it includes the tube sheath, is equipped with inner core 3 in the tube sheath, and the loop noose structure 2 that 3 front ends of inner core can zoom snare 1 is connected with snare 1, and handheld operation handle 6 is connected to 3 rear ends of inner core, and in the front end of tube sheath was located to snare 1, the rear end outside of tube sheath was located to handheld operation handle 6. The hand-held operating handle 6 is connected with the rear end of the tube sheath through a detachable structure 7.

The snare 1 is mainly used for snaring tissue specimens in hysteroscopy, and specifically, the adopted materials can use shape memory metal wires and the like. By designing the slipknot lasso structure 2 at the head end of the inner core 3, the snare 1 can be conveniently and freely zoomed, so that the snare 1 can be freely enlarged and reduced. The inner core 3 is a metal guide wire structure with certain hardness, which can be formed by shape memory metal wires, the head end of the inner core is connected with the slipknot lasso structure 2, and the tail end of the inner core is connected and fixed with the hand-held operating handle 6. The detachable structure 7 is a magnetic structure or a card slot structure.

The sheath is the structure that can stretch into hysteroscopy scope operation passageway, and the sheath includes sheath head 4 and sheath tail 5, and 4 rear ends of sheath head and 5 front ends of sheath tail are connected, and snare 1 is located in the front end of sheath head 4, and handheld operating handle 6 is connected with 5 rear ends of sheath tail. The sheath head 4 may be designed as a smooth-surfaced, substantially rigid, rigid structure, the purpose of which is primarily the primary operational channel of the core 3. The sheath tail section 5 can be formed by an elastic part with an elastic metal or other material spring structure; when the elastic part is not compressed, the length of the inner core 3 is consistent with that of the whole tube sheath; when the resilient portion is compressed, the inner core 3 may extend out of the sheath and form a snare loop. The whole device can freely shrink and enlarge the snare 1 through the compression and the relaxation of the part. The hand-held operation end 6 is a fixed part at the tail end of the inner core 3 and is a main part held by an operator; the position is connected with the tail end of the tube sheath through a magnetic structure/clamping groove structure, and an operator can fix the uterine cavity tissue and take out a specimen together with the whole tube sheath by pulling the structure.

As shown in fig. 2, the utility model is used as follows:

step 1, after the existing hysteroscopy scope is placed in the uterine cavity and the occupying tissues of the uterine cavity are exposed, the device of the utility model is placed in the operation channel of the hysteroscopy scope and is introduced into the uterine cavity;

step 2, pushing the snare 1 by holding the operating handle 6 to the head end of the tube sheath, pushing out the snare 1 and enabling the snare 1 to be enlarged (according to the material of the shape memory metal wire, after the constraint of the tube sheath is cancelled, the snare automatically returns to the original size), forming a snare loop, sleeving the snare loop into the uterine cavity space occupying tissue, and adjusting the position of the snare loop to enable the snare loop to be positioned at the pedicle of the space occupying tissue;

and 3, retreating and loosening the handheld operating handle 6 to enable the snare 1 to be retracted, tightened and fixed on the pedicel part of the uterine cavity space occupying tissue, pulling the handheld operating handle 6 outwards, pulling and cutting the space occupying tissue, and simultaneously taking out the specimen.
