Therefore, the following description should be understood as being broadly known to those skilled in the art and not as a limitation of the present invention.

[0038] The present invention is described in more detail in the following paragraphs by way of example with reference to the accompanying drawings. The advantages and features of the present invention will become more apparent from the following description. It should be noted that the accompanying drawings are in very simplified form and are not in exact proportions, and are only used to facilitate and clearly assist in illustrating the purpose of the embodiments of the present invention.

[0039] like Figure 1 As shown, an embodiment of the present invention provides a convenient and practical uterus fixator, comprising a slide rail 1, a fixing tube 2 and a fixing assembly 3.

[0040] Specifically, the slide rail 1 is used to be placed on the abdomen 100; the fixed tube 2 passes through the slide rail 1 and extends to the inside of the abdomen 100; the fixed tube 2 is slidably connected to the slide rail 1; the fixed component 3 is slidably arranged in the fixed tube 2; one end of the fixed component 3 can extend into the patient's uterus 200 to fix the uterus 200; the other end of the fixed component 3 extends to the outside of the fixed tube 2.

[0041] In one embodiment, continue to refer to Figure 1 As shown, the fixing assembly 3 includes a manipulation member 301, a connection member 302 and a clamping member.

[0042] Specifically, the operating member 301 passes through the fixed tube 2, one end of the operating member 301 is connected to the clamping member through a connecting member 302, and the other end extends to the outside of the fixed tube 2; one end of the connecting member 302 away from the operating member 301 is connected to the clamping member; a plurality of barbs 303 are provided on the clamping member; when fixed, the barbs 303 are inserted into the uterus 200 to fix the uterus 200.

[0043] Preferably, the connecting member 302 is a spiral structure.

[0044] By inserting the fixing tube 2 into the abdomen 100 and rotating the joystick, the connecting piece 302 of the spiral structure also rotates, and under the action of the spiral structure, the clamp is rotated into the uterus 200; the uterus 200 can be fixed by the provision of the barbs 303. When fixation is not required, only the barbs 303 need to be left in the uterus 200 (the connecting piece 302 outside the uterus 200 can be removed by cutting it with a scalpel), and the rest can be removed.

[0045] Suitable for those who need to undergo a 200 (partial) hysterectomy surgery later.

[0046] Preferably, Figure 2 As shown, the slide rail 1 is a cross-shaped slide rail 1. Specifically, the fixing tube 2 moves along the cross-shaped track of the cross-shaped slide rail 1, so as to fix the uterus 200 in a suitable position according to the actual needs of the operation, which is convenient for the laparoscopic operation.

[0047] In addition, since the slide rail 1 is directly placed on the abdomen 100 , the slide rail 1 can be rotated according to actual needs, so that the uterus 200 can move in any direction.

[0048] In a specific example, a limiting member is provided at one end of the fixed tube 2 away from the uterus 200 (the limiting member is not shown in the figure for simplicity of illustration) to prevent the fixed tube 2 from falling off from the slide rail 1 and entering the abdomen 100 .

[0049] Preferably, the diameter of the limiting member is greater than the width of the slide rail 1 .

[0050] In this embodiment, the fixing tube 2 and the slide rail 1 are first placed on the abdomen 100 , and the fixing tube 2 is inserted into the abdomen 100 ; and then the fixing assembly 3 is manipulated to fix the uterus 200 .

[0051] Regarding the specific fixation of the uterus 200, in one embodiment, continue to refer to Figure 1 As shown, if the setting of the fixing assembly 3 of the operating member 301, the connecting member 302 and the clamping member is adopted, then by extending the fixing tube 2 into the abdomen 100 and then rotating the operating rod, the connecting member 302 of the spiral structure will also rotate accordingly, and under the action of the spiral structure, the clamping member is rotated into the uterus 200; by the setting of the barbs 303, the uterus 200 can be fixed.

[0052] In addition, according to the surgical requirements, the uterus 200 can be fixed in a suitable position by moving the fixing tube 2 in various directions in the slide rail 1. After the fixing tube 2 is moved, the fixing tube 2 and the fixing assembly 3 are in an inclined state, and the fixing tube 2 can be manually supported to prevent the fixing tube 2 from being reset.

[0053] In another embodiment, if Figure 2-9 As shown, the fixing assembly 3 includes a fixing tube 311 , a connecting rope 312 and a plurality of fixing members 313 .

[0054] Specifically, the fixing tube 311 is located in the fixing tube 2, and one end extends to the outside of the fixing tube 2; the connecting rope 312 passes through the fixing tube 311, and one end is fixed to the outer wall of the fixing tube 311 by a fastener 314, and the other end is connected to the fixing member 313; the fixing member 313 is rotatably installed at the other end of the fixing tube 311; the opposite side walls of the multiple fixing members 313 are fitted together, and are opened under the pulling of the connecting rope 312 to fix the uterus 200.

[0055] In one embodiment, in combination Figure 3 and Figure 4 As shown, the outer wall of the fixing tube 311 is provided with a first slot 3110 and a second slot 3111. Specifically, the fastener 314 is located in the first slot 3110 or in the second slot 3111.

[0056] In this embodiment, combined with Figure 3 and Figure 5As shown, the end of the fixing member 313 away from the fixing tube 311 is provided with an inclined surface. Specifically, the inclined surfaces of the fixing members 313 form a tip 3130. The setting of the tip 3130 (similar to a needle) facilitates the fixing member 313 to enter the uterus 200.

[0057] As a preferred embodiment, the connecting rope 312 can be an elastic rope. When the fastener 314 is pulled out from the second slot 3111 , the plurality of fixing members 313 are closed and fitted together under the action of elastic force, thereby facilitating the removal of the fixing members 313 from the uterus 200 .

[0058] In addition, the cross section of the connecting rope 312 is Y-shaped. Figure 3-6 As shown, the two ends of the Y-shaped connecting rope 312 close to each other are respectively connected to the fixing member 313. The other end is located on the fixing tube 311. More specifically, a groove 3131 is provided on the side of the fixing member 313 close to the fixing tube 311, and the end of the connecting rope 312 away from the fixing tube 311 is fixed in the groove 3131. The side wall of the fixing tube 311 is provided with a plurality of through holes, and the end of the connecting rope 312 away from the fixing member 313 passes through the through holes.

[0059] like Figure 2-9 As shown, by setting the fixing tube 311, the connecting rope 312 and the plurality of fixing members 313, when the fixing tube 2 is extended into the abdomen 100, it is only necessary to push the fixing tube 311 to drive the fixing member 313 to move, and the fixing member 313 pierces the wall of the uterus 200 through the tip 3130 to enter the interior. Then, the fastener 314 is taken out from the first slot 3110, the connecting rope 312 is pulled, and the plurality of fixing members 313 are opened under the traction of the connecting rope 312 (the angle between the opposite side walls of the fixing members 313 is in the range of 0° to 90°, including 0° and 90°), and then the fastener 314 is placed in the second slot 3111 to fix the uterus 200.

[0060] When there is no need to fix the uterus 200, the fastener 314 is pulled out from the second slot 3111 and inserted into the first slot 3110. At this time, the fixing member 313 is no longer affected by the traction force of the connecting rope 312. Then the fixing tube 311 is pulled out to drive the fixing member 313 to move upward and remove it from the uterus 200.

[0061] In this embodiment, a limit clamp is provided on the fixing assembly 3 (for the sake of simplicity of illustration, the limit clamp is not shown in the figure), and a limit groove is provided in the fixing tube 2.

[0062] Specifically, the limiting clamp is slidably disposed in the limiting clamp slot to prevent the fixing assembly 3 from falling off from the fixing tube 2 .

[0063] In another embodiment, continue to refer to Figure 2-9 As shown, if the fixing assembly 3 of the fixing tube 311, the connecting rope 312 and the plurality of fixing members 313 is used, when the fixing tube 2 is inserted into the abdomen 100, it is only necessary to push the fixing tube 311 to drive the fixing member 313 to move, and the fixing member 313 pierces the wall of the uterus 200 through the tip 3130 to enter the interior. Then, the fastener 314 is taken out from the first slot 3110, the connecting rope 312 is pulled, and the plurality of fixing members 313 are opened under the traction of the connecting rope 312, and then the fastener 314 is placed in the second slot 3111 to fix the uterus 200.

[0064] When there is no need to fix the uterus 200, the fastener 314 is pulled out from the second slot 3111 and inserted into the first slot 3110. At this time, the fixing member 313 is no longer affected by the traction force of the connecting rope 312. Then the fixing tube 311 is pulled out to drive the fixing member 313 to move upward and remove it from the uterus 200.

[0065] In addition, according to the surgical requirements, the uterus 200 can be fixed in a suitable position by moving the fixing tube 2 in various directions in the slide rail 1. After the fixing tube 2 is moved, the fixing tube 2 and the fixing assembly 3 are in an inclined state, and the fixing tube 2 can be manually supported to prevent the fixing tube 2 from being reset.
