Description

Technical Field

[0001] This utility model relates to the technical field of cervical traction, specifically to a cervical fixation traction device. Background Technology

[0002] Cervical ligation, also known as cervical fixation, is a surgical procedure used to treat recurrent miscarriage or premature birth. This procedure involves ligating the cervix at the level of the internal os to prevent cervical dilation, thereby prolonging pregnancy and increasing fetal survival rates. It is important to note that cervical ligation is not suitable for all pregnant women and is generally only considered when there are clear indications.

[0003] According to Chinese Patent No. CN221635869U, a special instrument for cervical dilation and traction includes: two forceps handles connected movably between the two forceps handles by a locator; a connecting mechanism disposed on the forceps handles; the connecting mechanism includes dilation heads and connecting blocks; two dilation heads are respectively installed on the left side of the two forceps handles; two connecting blocks are respectively installed on the right side of the two forceps handles; a clamping handle is disposed on the right side of the connecting block; and a length adjustment mechanism disposed on the connecting block.

[0004] The above method uses clamps to fix the cervix for traction, but it still has the following disadvantages: when using clamps to fix the patient's cervix, there may be damage or bleeding caused by the tip of the clamp coming into contact with the inner wall of the patient's cervix, which reduces the safety of cervical traction. Utility Model Content

[0005] The purpose of this invention is to provide a cervical fixation and traction device to solve the problem of potential damage or bleeding caused by the tip of the clamp coming into contact with the patient's cervical wall, which reduces the safety of cervical traction operations.

[0006] To achieve the above-mentioned utility model objectives, the present utility model adopts the following technical solution: a cervical fixation traction device, including a handle, a sliding hole on one side of the handle, an installation groove inside the handle, a positioning rod fixed on one side of the installation groove, a sliding sleeve slidably inserted inside the sliding hole, the positioning rod and the sliding sleeve slidably inserted, a spring wrapped around the positioning rod, one end of the spring fixed to one side of the installation groove, the other end of the spring fixed to one end of the sliding sleeve, a fixing plate rotatably mounted on one end of the sliding sleeve, a ligating tube fixed on one side of the fixing plate, a sliding opening on one side of the fixing plate, the ligating tube slidably mounted to the sliding opening, and one end of the ligating tube fixed to one side of the handle.

[0007] Preferably, the top surface of the pull handle is fixed with a push port, the sliding sleeve is fixed with a connecting plate, the top surface of the connecting plate is fixed with a push plate, and the connecting plate and the push port are slidably configured.

[0008] Preferably, two positioning plates are fixed on one side of the fixing plate, and a rotating hole is opened on one side of the positioning plate. Two rotating columns are fixed on the surface of one end of the sliding sleeve, and the rotating columns are rotatably inserted into the rotating hole.

[0009] Preferably, a fixing hole is provided on one side of the pull handle, and a valve stem is fixedly inserted into the fixing hole. A connecting hole is provided at one end of the sleeve tube, and the valve stem is fixedly inserted into the connecting hole.

[0010] Preferably, a sealing cap is threaded onto the valve stem, and several anti-slip strips are fixed to the surface of the sealing cap.

[0011] Preferably, the handle has several fixing grooves, and an anti-slip arc plate is fixed inside the fixing groove.

[0012] Compared with existing technologies, the cervical fixation traction device using the above-mentioned technical solution has the following beneficial effects:

[0013] First, medical staff will anesthetize the patient to reduce pain and discomfort. Then, they will use a dilator to widen the cervix. Once the cervix is ​​sufficiently dilated, the medical staff will hold the handle and insert a gas-filled ligation tube into the cervix. The staff will then apply a force to the push plate towards the fixation plate, which will reduce the inner diameter between the ligation tube and the fixation plate, thereby adjusting the tightness of the ligation tube when ligating the patient's cervix. Because the handle, sliding sleeve, fixation plate, and ligation tube are all made of lightweight silicone, the risk of damage and bleeding to the patient's cervical tissue is reduced, increasing the safety of the procedure.

[0014] Second, when medical staff place the ligation tube on the surface of the cervix, they will adjust the degree of air filling inside the ligation tube according to the actual situation. This will allow the ligation tube to fit fully against the patient's cervix, thereby increasing the contact area and friction between the ligation tube and the patient's cervix.

[0015] Third, when it is not necessary to evacuate or inflate the ligation tube through the valve, medical staff will screw the sealing cap on the valve to prevent gas leakage inside the ligation tube. When the medical staff's hand is on the surface of the pull handle, the palm of the medical staff will contact the surface of the anti-slip arc plate. The anti-slip arc plate made of rubber increases the friction between the pull handle and the medical staff's palm, preventing the pull handle from slipping off the medical staff's palm and reducing the risk of accidents when using the traction device.

[0021] The preferred embodiments of this utility model will now be described in detail with reference to the accompanying drawings.

[0022] like Figures 1-3 As shown, the cervical fixation retractor includes a handle 1, a sliding hole 2 on one side of the handle 1, an installation groove 3 inside the handle 1, a positioning rod 4 fixed to one side of the installation groove 3, a sliding sleeve 5 slidably inserted inside the sliding hole 2, the positioning rod 4 and the sliding sleeve 5 slidably inserted, a spring 6 wrapped around the positioning rod 4, one end of the spring 6 fixed to one side of the installation groove 3, the other end of the spring 6 fixed to one end of the sliding sleeve 5, a fixing plate 7 rotatably mounted on one end of the sliding sleeve 5, a ligating tube 8 fixed to one side of the fixing plate 7, a sliding opening 9 on one side of the fixing plate 7, the ligating tube 8 and the sliding opening 9 slidably mounted, one end of the ligating tube 8 fixed to one side of the handle 1, a pushing opening 10 fixed to the top surface of the handle 1, a connecting plate 11 fixed to the sliding sleeve 5, a pushing plate 12 fixed to the top surface of the connecting plate 11, and the connecting plate 11 and the pushing opening 10 slidably mounted.

[0023] During use, medical staff will first anesthetize the patient to reduce pain and discomfort. Then, the medical staff will use a dilator to dilate the patient's cervix. Once the cervix is ​​dilated sufficiently, the medical staff will hold the surface of the pull handle 1 and then place the gas-filled ligation tube 8 onto the patient's cervix. The staff will then apply a force to the push plate 12 in the direction of the fixing plate 7, which will reduce the inner diameter between the ligation tube 8 and the fixing plate 7, thereby adjusting the tightness of the ligation tube 8 when ligating the patient's cervix. Furthermore, since the pull handle 1, sliding sleeve 5, fixing plate 7, and ligation tube 8 are all made of lightweight silicone, the risk of damage and bleeding to the patient's cervical tissue is reduced, increasing the safety during operation.

[0024] like Figure 3 and Figure 4 As shown, two positioning plates 13 are fixed on one side of the fixed plate 7. A rotating hole 15 is opened on one side of the positioning plate 13. Two rotating columns 14 are fixed on the surface of one end of the sliding sleeve 5. The rotating columns 14 are rotatably inserted into the rotating hole 15. Several fixing grooves 21 are opened on the pull handle 1. An anti-slip arc plate 22 is fixed inside the fixing groove 21.

[0025] During use, when it is not necessary to evacuate or inflate the ligation tube 8 through the valve 17, medical staff will screw the sealing cap 19 onto the valve 17 to prevent gas leakage inside the ligation tube 8. When the medical staff's hand is on the surface of the pull handle 1, the medical staff's palm will contact the surface of the anti-slip arc plate 22. The rubber anti-slip arc plate 22 increases the friction between the pull handle 1 and the medical staff's palm, preventing the pull handle 1 from slipping off the medical staff's palm and reducing the risk of accidents during the use of the traction device.

[0026] like Figure 2 and Figure 4 As shown, a fixing hole 16 is provided on one side of the pull handle 1, and a valve stem 17 is fixedly inserted inside the fixing hole 16. A connecting hole 18 is provided at one end of the sleeve tube 8. The valve stem 17 is fixedly inserted into the connecting hole 18. A sealing cap 19 is threaded onto the valve stem 17, and several anti-slip strips 20 are fixed on the surface of the sealing cap 19.

[0027] During use, when medical staff place the ligation tube 8 on the surface of the cervix, they will adjust the degree of air filling inside the ligation tube 8 according to the actual situation. This will allow the ligation tube 8 to fully fit the patient's cervix, thereby increasing the contact area with the patient's cervix and increasing the friction between the ligation tube 8 and the patient's cervix.

[0028] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
