[0001] This utility model belongs to the field of medical device technology, specifically relating to a vaginal surgical retractor. Background Technology

[0002] The indications for transvaginal surgery now essentially cover the diagnosis and treatment of all diseases of the female reproductive system. Therefore, higher demands are placed on the skills of the surgeons and the functionality of the surgical instruments. Transvaginal surgery typically requires the use of surgical vaginal dilators and vaginal retractors. Currently, the L-shaped vaginal retractor is commonly used clinically. The surgery usually requires three surgeons. Two surgeons hold the L-shaped vaginal retractor and symmetrically retract the vagina upwards and downwards to expose the surgical field, while another surgeon performs the surgical procedure. It is evident that the current surgical process requires a significant amount of manpower to maintain vaginal retraction, resulting in high labor intensity and wasted human resources.

[0003] This invention addresses the aforementioned problems by providing a vaginal surgical retractor. Utility Model Content

[0008] The first connecting part and the second connecting part are slidably connected;

[0009] A fixing component is connected to the first connecting part and the second connecting part, wherein the fixing component has a released state and a locked state. In the released state, the front wall hook and the rear wall hook can move relative to each other and can move closer or further away from each other. In the locked state, the distance between the front wall hook and the rear wall hook is determined.

[0010] In some embodiments of this application, the first connecting portion includes:

[0011] The first connecting arm and the second connecting arm are arranged in a mirror image of each other;

[0012] A connector is located between the first connecting arm and the second connecting arm, and is rotatably connected to one end of the first connecting arm and one end of the second connecting arm. The connector has a mounting groove, and the connector is connected to the second connecting part through the mounting groove.

[0022] The support portion has a receiving groove, wherein a straight segment is inserted into the receiving groove and can slide along the length extension direction of the receiving groove, so that the overall length between the holding portion and the support portion is extended.

[0023] Furthermore, it also includes: a locking member, wherein the outer wall of the support portion is provided with a rectangular groove in the direction of the receiving groove, the outer wall of the straight segment is provided with a cylindrical shaft, the cylindrical shaft extends out of the rectangular groove, the locking member is connected to the cylindrical shaft and can abut against the outer wall of the support portion.

[0024] Furthermore, there is a threaded fit between the locking element and the cylindrical shaft.

[0025] The beneficial effects of this utility model are:

[0026] 1. By setting up anterior and posterior wall hooks that are connected to each other and can move relative to each other, as well as fasteners, during use, the anterior and posterior wall hooks are inserted into the patient's vagina. Then, in the released state, the distance between the anterior and posterior wall hooks is adjusted to pull the patient's vagina open. Then, the fasteners are switched to the locked state, so that the patient's vagina is always in a pulled-open state during the operation. This allows a doctor to pull open the patient's vagina during the operation to expose the surgical field. Compared with the traditional surgical area pulling method, it saves manpower and avoids the waste of human resources.

[0027] 2. By setting a front wall retractor that includes a retractor body and an extension, the extension can be pushed out of the retractor body during use, thereby extending the length of the retractor body.

Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0038] Figure 1 —2 illustrates the main technical content of this embodiment. This specific embodiment provides a vaginal surgical retractor, which includes:

[0039] Front wall hook 1, the front wall hook 1 has a rotatable first connecting part 14;

[0040] Rear wall hook 2, the rear wall hook 2 has a second connecting part 21;

[0041] The first connecting part 14 and the second connecting part 21 are slidably connected;

[0042] The fixing component is connected to the first connecting part 14 and the second connecting part 21. The fixing component has a released state and a locked state. In the released state, the front wall hook 1 and the rear wall hook 2 can move relative to each other and can move closer or further away from each other. In the locked state, the distance between the front wall hook 1 and the rear wall hook 2 is determined.

[0043] In use, first adjust the fixation component to the released state and bring the anterior wall retractor 1 and posterior wall retractor 2 close together. Then, the surgeon inserts the anterior wall retractor 1 and posterior wall retractor 2 into the patient's vagina and moves them away from each other to retract the vagina. After fully exposing the surgical field, the fixation component is switched to the locked state, which fixes the positional relationship between the anterior wall retractor 1 and posterior wall retractor 2 to maintain the retraction state during the operation. Then, a doctor supports the instrument while the surgeon performs the operation.

[0044] refer to Figure 1 —3 and Figure 7 —8, In this embodiment, the anterior wall hook 1 includes: a holding part 11 and a supporting part 12. The holding part 11 is composed of a bent section 111 and a straight section 112, wherein the straight section 112 is disposed at one end of the bent section 111. The supporting part 12 has a receiving groove 121, wherein the straight section 112 is partially inserted into the receiving groove 121 and can slide along the length extension direction of the receiving groove 121, so that the overall length between the holding part 11 and the supporting part 12 is extended. In use, the straight section 112 is pushed to slide in the receiving groove 121. At this time, the bent part gradually moves away from the supporting part 12, so that the bent part can penetrate deeper into the patient's body to hold more human tissue, thereby further expanding the surgical field of view and avoiding the influence of the surrounding tissues on the surgical operation.

[0045] refer to Figure 2 —3, more specifically, it also includes: a locking member 13, wherein a rectangular groove is provided on the outer wall of the support part 12 toward the receiving groove 121, and a cylindrical shaft 1121 is provided on the outer wall of the straight section 112. The cylindrical shaft 1121 extends out of the rectangular groove, and the locking member 13 is connected to the cylindrical shaft 1121 and can abut against the outer wall of the support part 12; more specifically, the locking member 13 and the cylindrical shaft 1121 are threaded together. In use, by screwing the locking member 13, the locking member 13 abuts against the outer wall of the support part 12, thereby fixing the moving position of the straight section 112 within the receiving groove 121.

[0046] In addition, the first connecting part 14 is rotatably connected to the support part 12.

[0047] In this embodiment, the first connecting part 14 includes: a first connecting arm 141, a second connecting arm 142, and a connector 143; the first connecting arm 141 and the second connecting arm 142 are mirror images of each other; the connector 143 is located between the first connecting arm 141 and the second connecting arm 142, and is rotatably connected to one end of the first connecting arm 141 and one end of the second connecting arm 142, wherein the connector 143 has a mounting groove, and the connector 143 is connected to the second connecting part 21 through the mounting groove. In use, by applying force to the anterior wall hook 1 or the posterior wall hook 2, the two move relative to each other, thereby pulling open the patient's vagina.

[0048] refer to Figure 2 —3. More specifically, the first connecting arm 141 and the second connecting arm 142 are both connected to the support part 12 and are located on both sides of the support part 12 respectively. The first connecting arm 141 and the second connecting arm 142 are rotatably connected to the support part 12, so that the support part 12 can rotate relative to the rear wall hook 2, thereby making it easier for the holding part 11 to enter the patient's vagina, so as to better hold the vaginal tissue.

[0049] Specifically, the cross-sectional shape of the second connecting part 21 is the same as the cross-sectional shape of the mounting groove, and the mounting groove has a notch. The second connecting part 21 is inserted into the mounting groove through the notch, thereby forming a connection between the two.

[0050] In this embodiment, the connector 143 also has a through hole, and the second connecting part 21 has a connecting groove. The fixing component passes through at least part of the through hole and the connecting groove. When the front wall hook 1 or the rear wall hook 2 is subjected to force, the fixing component slides in the connecting groove, thereby enabling translation between the front wall hook 1 and the rear wall hook 2.

[0051] refer to Figure 1—6. In this embodiment, the fixing component includes: a limiting shaft 15 and a fastener 16. One end of the limiting shaft 15 passes through a through hole and a connecting groove. The limiting shaft 15 has a first blocking end and a second blocking end. In the locked state, the first blocking end abuts against the outer wall of the connector 143. In the released state, the first blocking end moves away from the connector 143. The fastener 16 is connected to the limiting shaft 15 and can move closer to or away from the first blocking end along the axial direction of the limiting shaft 15. In the locked state, the fastener 16 abuts against the outer wall of the second connecting portion 21 and makes the first… The blocking end abuts against the outer wall of the connector 143. When the fastener 16 is switched from the locked state to the released state, it moves away from the first blocking end. In use, the anterior wall hook 1 and the posterior wall hook 2 are adjusted to the appropriate distance according to the surgical requirements to pull open the patient's vagina. Then the fastener 16 is rotated so that the fastener 16 abuts against the outer wall of the second connecting part 21 and the first blocking end of the limiting shaft 15 abuts against the outer wall of the connector 143. At this time, the coefficient of friction between the inner wall of the connector 143 and the outer wall of the second connecting part 21 increases, so that the two cannot be displaced relative to each other.

[0052] More specifically, there is a threaded fit between the fastener 16 and the limiting shaft 15.

[0053] More specifically, the first blocking end includes a first baffle, and the second blocking end includes a second baffle. Both the first baffle and the second baffle are fixedly connected to the limiting shaft 15. More specifically, the first baffle is a circular plate, wherein the diameter of the first baffle is larger than the outer diameter of the limiting shaft 15. Under this setting, when the fastener 16 is screwed toward the first baffle, the first baffle will not come out of the through hole.

[0054] How to use this utility model:

[0055] 1. First, adjust the fixation components to the released state and bring the anterior wall retractor and posterior wall retractor close together. Then, the surgeon inserts the anterior wall retractor and posterior wall retractor into the patient's vagina and moves them away from each other.

[0056] 2. After fully exposing the surgical field, the fixation components are switched to the locked state, so that the positional relationship between the anterior wall retractor and the posterior wall retractor is fixed, thereby maintaining the retraction state during the operation.

[0057] 3. When it is necessary to further expand the deep field of vision of the surgical area, push the straight segment to slide in the receiving groove. At this time, the bent part gradually moves away from the support part, so that the bent part can penetrate deeper into the patient's body to hold more human tissue, thereby expanding the surgical field of vision and avoiding the influence of the surrounding tissues on the surgical operation.

[0058] The above description of the embodiments is only for understanding the present invention. It should be noted that those skilled in the art can make several improvements to the present invention without departing from the principle of the present invention, and these improvements will also fall within the protection scope of the claims of the present invention.
