[0028] It should be noted that: similar reference numbers and letters represent similar items in the following drawings, so once an item is defined in one drawing, it does not need to be further defined and explained in subsequent drawings.

[0029] As shown in Figure 1 The present embodiment proposes a silica gel sheath type damage prevention uterine curettage device, which comprises a sleeve rod 1, a protection assembly 2 is fixedly arranged on the outer side of the sleeve rod 1 to prevent dirt from penetrating, and a cleaning assembly 3 for uterine curettage is arranged on one side of the sleeve rod 1.

[0030] As shown in Figure 2 The protection assembly 2 comprises a silica gel cylinder 201 sleeved with the outer side wall of the sleeve rod 1, the silica gel cylinder 201 is embedded with an elastic support wire 204, the end of the silica gel cylinder 201 is fixedly connected with a sealing ring 202, the inner side wall of the sealing ring 202 is provided with a flexible sealing lip and is in close contact with the outer side wall of the sleeve rod 1, the top of the sleeve rod 1 is provided with a sliding piece 203, and the sliding piece 203 is fixedly connected with the inner side wall of the silica gel cylinder 201. During use, since the flexible sealing lip of the sealing ring 202 is in close contact with the outer side wall of the sleeve rod 1, dirt generated during uterine curettage operation cannot enter the gap between the silica gel cylinder 201 and the sleeve rod 1, accumulation of dirt in the gap is avoided, the difficulty of subsequent cleaning is reduced, the cleanliness of the inside of the device is ensured, long-term stable use of the device is facilitated, after uterine curettage operation is completed, the user can operate the sliding piece 203, the silica gel cylinder 201 is driven by the sliding piece 203 to move synchronously, the end of the sleeve rod 1 is completely wrapped inside the silica gel cylinder 201, and then the whole device is taken out from the patient's body. At this time, the outer wall of the silica gel cylinder 201 is in flexible contact with the passage in the patient's body, avoiding damage caused by direct scraping of the tissue by metal or hard components during the taking-out process. The elastic support wire 204 is made of a shape memory alloy material, which is pre-set in a relaxed spiral shape in a body temperature environment, can better maintain the shape of the silica gel cylinder 201, prevent it from wrinkling, effectively reduce the adsorption and adhesion between the silica gel cylinder 201 and the human tissue, make the advancing and retreating operation smoother, and reduce the risk of tissue damage.

[0031] As shown in Figure 2 and Figure 5As shown, the cleaning component 3 includes a suction pipe 301 fixedly installed inside the sleeve rod 1, a U-shaped tube 302 fixedly connected to the end of the sleeve rod 1, a scraping blade 303 fixedly installed at the bottom of the U-shaped tube 302, the two ends of the U-shaped tube 302 being connected to the suction pipe 301, multiple suction ports 304 being opened on the side wall of the U-shaped tube 302, and a miniature high-frequency vibrator 305 fixedly installed inside the U-shaped tube 302. In use, the suction tube 301 is connected to the external suction device. The curettage blade 303 installed at the bottom of the U-shaped tube 302 scrapes away the uterine wall tissue. At the same time, multiple suction ports 304 on the side wall of the U-shaped tube 302 work simultaneously to quickly remove tissue fragments, blood and secretions generated during the scraping process. These contaminants are discharged from the body through the suction tube 301, preventing contaminants from accumulating in the uterine cavity or spreading to other areas. The contaminants are removed quickly and thoroughly. The miniature high-frequency vibrator 305 is a miniature eccentric rotor motor or piezoelectric ceramic actuator that meets the biocompatibility requirements of medical devices. The vibration generated by the miniature high-frequency vibrator 305 is transmitted to the silicone tube 201 through the U-shaped tube 302 and the sleeve 1, which indirectly solves the problem of local adsorption and adhesion between the silicone tube 201 and human tissue due to surface wettability, making the instrument move more smoothly and further reducing traction damage to normal tissues.

[0032] like Figure 5 As shown, the suction tube 301 passes through the sleeve rod 1 and extends to one side of the sleeve rod 1, with the end of the suction tube 301 located inside the U-shaped tube 302. When the external medical suction device is activated, it generates negative pressure, which is transmitted through the suction tube 301 connected to the suction device. This negative pressure can be directly and efficiently transmitted to the internal space of the U-shaped tube 302, allowing the suction tube 301 to promptly remove tissue fragments, blood, and secretions generated during the scraping process.

[0033] like Figure 5 As shown, multiple suction ports 304 are located on the inner arc surface of the U-shaped tube 302, and the curettage blade 303 is located below the multiple suction ports 304. During the scraping of tissue by the curettage blade 303, tissue fragments, blood, secretions, and other waste are simultaneously attracted by the negative pressure at the multiple suction ports 304 on the inner arc surface of the U-shaped tube 302 and are quickly sucked into the U-shaped tube 302. Subsequently, the waste flows along the channel of the U-shaped tube 302 and is finally discharged from the body through the suction tube 301 connected to the U-shaped tube 302, maintaining a clean environment in the uterine cavity.

[0034] like Figure 4As shown, the sliding member 203 includes a connecting rod 2031 fixedly installed with the inner side wall of the silica gel cylinder 201, and the other end of the connecting rod 2031 is fixedly connected with a sliding block 2032. After the operation of the uterine curettage is completed, the user continues to operate the sliding block 2032 to move the sliding block 2032 in a specific direction, drives the silica gel cylinder 201 to move to the end of the sleeve rod 1 through the connecting rod 2031, and finally completely wraps the U-shaped tube 302 and the curettage blade 303 at the end of the sleeve rod 1 inside the silica gel cylinder 201. At this time, the outer wall of the silica gel cylinder 201 forms a flexible contact with the passage in the patient's body, and prepares for the subsequent device to be taken out.

[0035] As shown in Figure 4 The outer side wall of the sleeve rod 1 is provided with a limiting groove 4, and the sliding block 2032 slides in the limiting groove 4. The limiting groove 4 provides a clear movement track for the sliding block 2032, so that the sliding block 2032 can only slide in a predetermined direction, avoiding the silica gel cylinder 201 from moving excessively and damaging the patient during operation.

[0036] As shown in Figure 3 The end of the sleeve rod 1 is fixedly connected with a handle 5, and the handle 5 is located on one side of the sliding block 2032. When in use, the user can control the device to perform the uterine curettage operation through the handle 5, and a plurality of groups of rubber anti-skid pads are uniformly sleeved on the handle 5, which can prevent the handle 5 from slipping from the user's hand.

[0037] Specifically, the silica gel sheathed anti-injury uterine curettage device in use: as shown in Figure 2 and Figure 5As shown, the suction pipe 301 is connected with the external suction device, the uterine curettage blade 303 installed at the bottom of the U-shaped pipe 302 scrapes the uterine wall tissue, and meanwhile, a plurality of groups of suction ports 304 on the side wall of the U-shaped pipe 302 work synchronously to quickly suck the tissue fragments, blood and secretions generated in the scraping process, which are discharged out of the body through the suction pipe 301, so that the pollutants are prevented from accumulating in the uterine cavity or spreading to other areas, the pollutants are quickly and completely removed, the relative clean surgical environment in the uterine cavity is maintained, and due to the close adhesion of the flexible sealing lip of the sealing ring 202 to the outer side wall of the sleeve rod 1, the pollutants generated in the uterine curettage operation cannot enter the gap between the silicone barrel 201 and the sleeve rod 1, the accumulation of the pollutants in the gap is avoided, the difficulty of subsequent cleaning is reduced, the cleanliness of the inside of the device is ensured, the long-term stable use of the device is facilitated, after the uterine curettage operation is completed, the user can operate the sliding piece 203, the silicone barrel 201 is driven by the sliding piece 203 to move synchronously, the end of the sleeve rod 1 is completely wrapped in the inside of the silicone barrel 201, and then the whole device is taken out of the patient's body, at this time, the outer wall of the silicone barrel 201 is in flexible contact with the channel in the patient's body, the model of the micro high-frequency vibrator 305 is a micro eccentric rotor motor or a piezoelectric ceramic actuator meeting the biological compatibility requirements of medical devices, the vibration generated by the micro high-frequency vibrator 305 is transmitted to the silicone barrel 201 through the U-shaped pipe 302 and the sleeve rod 1, thereby indirectly solving the problem of local adsorption and adhesion of the silicone barrel 201 due to the surface wettability and human tissue, making the movement of the instrument more smooth, and further reducing the pulling damage to normal tissues.

[0038] All the technical features in the embodiment can be freely combined according to actual needs.

[0039] The above embodiment is a preferred implementation scheme of the utility model, and the utility model can also be implemented in other ways, and any obvious replacement without departing from the technical scheme concept is within the protection scope of the utility model.
