A monolithic hysteroscope instrument operation pusher

Abstract

The present invention discloses a monolithic hysteroscope instrument operation pusher, which includes a pusher body that can be attached and connected to the hysteroscope body. The instrument can smoothly pass through the blind areas such as the vagina and cervical canal along the hysteroscope body that has entered the uterine cavity by means of the groove on the pusher body. After the instrument is sent into the uterus, continuous and flexible treatment operations can be carried out. The present invention facilitates doctors to quickly, accurately and non-invasively send the treatment instrument into the uterus, not only reducing the treatment cost, but also achieving good treatment effects.

Description

Technical Field

[0001] The present invention relates to a hysteroscopic surgical treatment system, and particularly to a device attached to a hysteroscope examination lens body to assist instruments in entering the uterine cavity. Background Art

[0002] During the hysteroscopic treatment process, commonly used resectoscopes, treatment lenses, and shaving systems have in common that the examination lens body and multiple treatment instruments are wrapped together, resulting in a relatively thick entire instrument system, often requiring cervical dilation to more than 8 mm. Moreover, the instruments for treatment operations generally have a delicate structure, are often expensive, easily damaged, and have complex and time-consuming operations, making it difficult to carry out hysteroscopic surgeries using these systems in outpatient clinics.

[0003] During the hysteroscopic examination process, even if polyps, embryonic residues, or intrauterine adhesions are found in the uterine cavity, since treatment instruments such as scissors and forceps are not easily passed through blind areas such as the vagina and cervical canal alone, it poses relatively high skill requirements for doctors to further carry out hysteroscopic treatment. In addition, since the front ends of scissors and forceps are sharp and easy to scratch the vaginal and cervical canal mucosae, there are many limiting factors in widely carrying out hysteroscopic surgeries in outpatient clinics.

[0004] Chinese Patent CN201379632Y discloses a uterine cavity surgical instrument, which forms a system by arranging uterine cavity forceps in a manner that can move synchronously with the hysteroscope and can be independently operated at the same time. It can ensure that the entry and operation of the instrument are under the monitoring of the hysteroscope, but when replacing the instrument, the hysteroscope needs to be withdrawn together, resulting in a still relatively long treatment process, and the operation range of the instrument is limited, resulting in frequent replacement of the hysteroscopic field of view, reducing the continuity of operation and affecting the treatment effect. Summary of the Invention

[0005] The purpose of the present invention is to provide a simple-structured and convenient-to-use monolithic hysteroscopic instrument operation pusher.

[0006] To achieve the above purpose, the present invention adopts the following technical solutions:

[0007] The pusher includes a columnar pusher body. On one side surface of the columnar pusher body, there is a card slot for fitting with the side wall of the hysteroscope lens body, and on the other side surface of the columnar pusher body, there is a guiding groove extending along the axial direction of the hysteroscope lens body (the transverse section can be arc-shaped).

[0008] Preferably, the transverse section of the card slot (specifically referring to the contact surface between the columnar pusher body and the hysteroscope lens body) is arc-shaped (the radian is greater than π, which can make the columnar pusher body firmly attached to the hysteroscope lens body and prevent the columnar pusher body from falling off).

[0009] Preferably, the length of the columnar pusher body is less than the length of the hysteroscope lens body.

[0010] Preferably, a push-pull handle for sliding the card slot relative to the hysteroscope body is provided on the columnar pusher (facilitating grasping and operation).

[0011] Preferably, the push-pull handle is provided on one end face of the columnar pusher, and the other end face of the columnar pusher is close to the front end (the inspection image acquisition end) of the hysteroscope body (compared with the end face where the aforementioned push-pull handle is located).

[0012] Preferably, the surface portion of the columnar pusher between the openings of the card slot and the guiding groove protrudes outward (constituting the remaining surface of the columnar pusher except for the card slot, the guiding groove, and the end face), and the protruding surface portion is divided into two sections symmetrically distributed along the longitudinal section of the columnar pusher (with the axial direction of the hysteroscope body as the longitudinal direction), and the transverse section of each section of the outwardly protruding surface is arc-shaped.

[0013] Preferably, the pusher can be used in cooperation with a speculum or without a speculum; for example, the hysteroscope body, the columnar pusher, and the instrument can enter the uterine cavity through the speculum, or the vaginal endoscopy technique can be adopted without using a speculum, directly insert the hysteroscope body, and after the hysteroscope body enters the uterine cavity, then use the columnar pusher to send the instrument into the uterine cavity.

[0014] The beneficial effects of the present invention are reflected in:

[0015] In the present invention, the guiding groove can be introduced and fixed in the channel entering the uterine cavity along the hysteroscope body by using the card slot of the columnar pusher, so that the instrument can be quickly, accurately, and non-invasively sent into the uterine cavity without hysteroscope monitoring. Once the front end of the instrument enters the hysteroscope monitoring area, the doctor can continuously complete the surgical operations on the lesions (polyps, embryonic residue, or intrauterine adhesions existing in the uterine cavity) at different angles and depths within a certain visual field (with a larger operation range and stronger flexibility), making the treatment process simple, without the need for cervical dilation or reducing the cervical dilation size, the operation process is also safer, reducing the treatment cost and time, alleviating the degree of treatment pain, and corresponding surgical operations can be completed in the outpatient department. At the same time, the popularization and application of the present invention can also reduce the cost of the instrument (simpler-structured instruments can be used, and the instrument does not require complex and delicate structural design).

[0016] Furthermore, in the present invention, the card slot and the outer convex surface between the guiding groove and the card slot are both arc surfaces without edges and corners. Combined with the use of the guiding groove, the entry processes of the pusher and the instrument along the hysteroscope body are relatively smooth, avoiding damage to normal tissues such as the uterine cavity.

[0021] The present invention will be further described in detail below with reference to the drawings and embodiments.

[0022] See Figure 1 , Figure 2 and Figure 3 , the hysteroscope instrument operation pusher of the present invention includes a pusher body 2. One side surface of the pusher body 2 is a concave large semi-cylindrical surface, forming a card slot of the pusher body 2. The pusher body 2 can be reliably attached to the hysteroscope body 1 through the card slot. The other side surface of the pusher body 2 (the back of the card slot) has a groove 2-2 that facilitates the insertion of an instrument with a sharp front end along the hysteroscope body 1 into the uterine cavity (the front end of the instrument moves along the groove). The surface part of the pusher body 2 between the opening of the card slot and the opening of the groove 2-2 is an outwardly convex arc shape, which not only reduces the rubbing against surrounding tissues but also can separate the surrounding tissues from the groove 2-2 to avoid the situation where the instrument and the surrounding tissues are hooked at the position of the groove. The pusher body 2 is about 100 mm long (the length of the hysteroscope body is about 200 mm) and can be processed and formed from stainless steel material. In order to conveniently adjust the distance between the front end of the pusher body 2 and the front end 1-2 of the hysteroscope body after the pusher body 2 is stuck on the hysteroscope body 1 (for example, after observing the pusher body 2 in the hysteroscope monitoring area), a square handle 2-1 is provided at the rear end of the pusher body 2. The front end of the pusher body 2 can be processed into an arc shape, which is convenient for the movement of the pusher body 2 (for example, reducing the hooking and dragging with surrounding tissues when entering the uterine cavity), and can also reduce the occlusion of the hysteroscope monitoring area (especially when the front end of the pusher body 2 is close to or overlaps with the front end 1-2 of the mirror body), so that the groove 2-2 can be positioned at an appropriate position, thereby giving full play to the guiding role during the movement of the instrument.

[0023] During hysteroscopic surgery, first install (press or sleeve) the pusher body 2 on the rear end 1-1 of the mirror body through its card slot, and then insert the hysteroscope body 1 into the uterus. During hysteroscopic examination, when polyps, retained fetal substances, or intrauterine adhesions are found in the uterine cavity, instruments can be inserted for treatment operations. At this time, depending on the width of the internal os of the cervix, stop the front end 1-2 of the mirror body in the uterine cavity or at the internal os of the cervical canal. Use the handle 2-1 to push the front end of the pusher body 2 into the front end 1-2 of the mirror body until the front end of the pusher body 2 can be seen on the display of the hysteroscope. Slightly push and pull back and forth to adjust the position of the front end of the pusher body 2 (to ensure that the visual field of the hysteroscopic monitoring area on the display remains good before and after the instrument enters along the groove 2-2). Place the tip of the scissors or forceps of the laparoscope into (for example, snap into) the rear end of the groove 2-2, and send the forceps or scissors along the groove 2-2 to the front end of the pusher body 2 and slide out. The forceps or scissors can be seen entering the uterus on the display of the hysteroscope, and then normal treatment operations can be performed. When replacing the instruments for treatment operations, withdraw the currently used instrument, and then repeat the above method of inserting the instrument to continue the new treatment operation.

[0024] During hysteroscopic examination, when polyps, retained fetal substances, or intrauterine adhesions are found in the uterine cavity and treatment instruments need to be inserted, by using the above-mentioned pusher, the front ends of these instruments can smoothly slide into the uterus along the groove 2-2 that has entered and is positioned on the surface of the hysteroscope body 1 when passing through blind areas such as the vagina and cervical canal. Therefore, the interval time between treatment operations can be shortened, and since there is no need to use a device that integrates the hysteroscope body 1 and the instrument, only when the cervical os is about 6 mm, some routine treatments basically do not require cervical dilation, which can reduce the pain of the patient during the operation, avoid hospitalization, and at the same time, the operation of the instrument is less restricted and can be continuously and flexibly operated under the hysteroscopic field of view provided by the display. In addition, it can also meet the objective requirements for the durability and availability of treatment instruments, and choose to use treatment instruments with a simpler structure and a thicker size (making the instrument easy to operate and not easy to damage).

[0025] In summary, the hysteroscopic instrument operation pusher described in the present invention facilitates the doctor to quickly, accurately, and non-invasively insert the treatment instrument into the uterus, and the treatment process can be completed in the outpatient operating room, which not only reduces the treatment cost but also can achieve good treatment effects.
