Description

Technical Field

[0001] This utility model relates to the field of cervical instruments, specifically an electrocautery cup-type uterine lifter. Background Technology

[0002] Uterine lifters are commonly used medical devices in gynecological surgery. Through mechanical support, they lift and hold the uterus in a specific position, fully exposing the surgical area within the pelvic cavity for easier observation and manipulation by the doctor. For example, Chinese utility model patent CN219613992U discloses a uterine lifter comprising a lifter body with multiple ventilation slots surrounding its outer wall. A square tube is connected to the outer wall of each ventilation slot. A housing is located on the outer wall of the lifter body, and its inner wall houses a power supply component, a miniature fan, a heating chamber, and a heating rod. While similar in overall structure to conventional uterine lifters, this type of lifter presents the following problems: When transectioning the uterine body, monopolar electrocoagulation or an ultrasonic scalpel is required to cut around the rim of the lifter cup. However, for significantly enlarged uteri, exposing the rim is difficult, leading to difficulty in transection and increasing the risk of excessive bleeding and even rectal injury. Utility Model Content

[0003] The purpose of this invention is to provide an electro-cutting cup-type uterine lifter. This invention uses a retractable elastic electrode needle located on the rim of the uterine lifter cup to stably cut the uterine body, and features convenient and quick operation and high cutting efficiency.

[0004] The technical solution of this utility model is as follows: an electric cutting cup-type uterine lifter, comprising a myoma drill assembly, a uterine lifter frame, and a uterine lifter cup. The gap between the myoma drill assembly and the uterine lifter frame forms an annular channel. The uterine lifter cup has a set of symmetrical bent channels, the outer opening of which is located at the edge of the cup. One end of the bent channel is connected to the annular channel. An elastic electrode needle that can extend outward from the uterine lifter cup is provided in the bent channel. A push button is provided on the surface of the uterine lifter frame. One end of the push button is connected to a rope, which passes through the annular channel and the bent channel and is connected to the end of the elastic electrode needle.

[0005] In the aforementioned electrocautery cup-type uterine lifter, the bent channel includes an axial channel disposed within the uterine lifter cup, one end of the axial channel having an oblique channel connected to an annular channel, and one end of the axial channel having a needle body channel connected to the outside of the uterine lifter cup, wherein the elastic electrode needle is disposed within the needle body channel.

[0006] In the aforementioned electric cutting cup-type uterine lifting device, the connection between the axial channel and the oblique channel, as well as the connection between the axial channel and the needle body channel, are provided with transition arcs.

[0007] In the aforementioned electrocautery cup-type uterine lifter, the elastic electrode needle includes a needle head disposed in the needle body channel, a limiting protrusion on the circumferential surface of the needle head, a spring sleeved on the needle head, one end of the spring abutting against the limiting protrusion, and the other end of the spring abutting against the limiting ring on the inner wall of the needle body channel.

[0008] In the aforementioned electrocautery cup-type uterine lifter, the push button includes a ring plate disposed in an annular channel, the ring plate having a button body, the two ends of the button body having elastic strips, and the ends of the elastic strips having arc-shaped blocks; the surface of the uterine lifter has a transverse groove, and the two ends of the transverse groove have arc-shaped grooves that cooperate with the arc-shaped blocks.

[0009] In the aforementioned electric cutting cup-type uterine lifter, the upper end of the button body has a thin sheet with an attached anti-slip layer.

[0010] Compared with the prior art, the advantages of this utility model are:

[0011] 1. In this invention, the elastic electrode needle is initially hidden within the curved channel of the uterine cup. After the uterine body is freed, a push button is used to pull the elastic electrode needle through a rope, causing it to quickly extend and puncture the vaginal fornix tissue. Simultaneously with the rotation of the uterine cup, the elastic electrode needle rotates, cutting the uterine body. The cut uterine body is collected by the uterine cup. After cutting, the elastic electrode needle retracts into the curved channel under the pull of the push button. The retractable elastic electrode needle, located at the rim of the uterine cup, stabilizes the cutting of the uterine body. The operation is convenient and quick, requiring no additional monopolar electrocoagulation or ultrasonic scalpel assistance, reducing instrument changes, shortening surgical time, and improving surgical efficiency. The electrode needle forms a precise cutting path along the rim of the uterine cup. Even for a significantly enlarged uterine body, the cutting boundary can be exposed through active puncture of the electrode needle, avoiding the risks of excessive wound bleeding and damage to adjacent organs caused by the difficulty of traditional cup rim exposure, thus improving surgical safety.

[0012] 2. In the push-type button, the arc-shaped block at the end of the elastic strip can correspond to the corresponding arc-shaped groove, allowing the surgeon to extend or retract the positioning needle by pushing or pulling with one hand, reducing instrument adjustment time and improving surgical continuity.

[0013] 3. The elastic electrode needle assembly adopts a split and detachable structure, and the needle, spring and other components can be disassembled and disinfected independently, making installation and maintenance convenient. Attached Figure Description

Detailed Implementation

[0020] The present invention will be further described below with reference to the accompanying drawings and embodiments, but this should not be construed as limiting the present invention.

[0021] Example: An electrocautery cup-type uterine lifter, comprising a myoma drill assembly 1, a uterine lifter frame 2, and a uterine lifter cup 3, as shown in the attached diagram. Figure 1 As shown, these structures are all existing conventional technologies, and their structures and the connections between the components will not be described in detail here. The gap between the fibroid drill assembly 1 and the uterus lifter 2 forms an annular channel 5; the uterus lifter 3 has a set of symmetrical bent channels 6, the outer opening of the bent channels 6 is located at the edge of the uterus lifter 3, and one end of the bent channels 6 is connected to the annular channel 5; the bent channels 6 are equipped with elastic electrode needles 7 that can extend out of the uterus lifter 3 and are connected to a power source. Because it is necessary to use the elastic electrode needles to cut the uterine body, it is necessary to generate heat through high-frequency current and act on the elastic electrode needles. After the elastic electrode needles extend into the uterus lifter, they will be at the edge of the uterus lifter, as shown in the attached figure. Figure 2 As shown, the bent channel 6 includes an axial channel 10 disposed within the uterine cup 3, as illustrated in the attached diagram. Figure 3 As shown, one end of the axial channel 10 has an oblique channel 11 connected to the annular channel 5, and the other end of the axial channel 10 has a needle body channel 12 connected to the outside of the uterine cup 3. An elastic electrode needle 7 is disposed within the needle body channel 12. The needle body channel is inclined at a certain angle along the radial direction of the uterine cup, with this angle ranging from 5 to 10 degrees. The connection points between the axial channel 10 and the oblique channel 11, as well as between the axial channel 10 and the needle body channel 12, both have transition arcs 13. These transition arcs prevent the rope from being cut, reduce wear, and extend service life. The elastic electrode needle 7 includes a needle tip 14 disposed within the needle body channel 12, as shown in the attached diagram. Figure 4As shown, the needle 14 has a limiting protrusion 15 on its circumferential surface, and a spring 16 is fitted on the needle 14. One end of the spring 16 abuts against the limiting protrusion 15, and the other end of the spring 16 abuts against the limiting ring on the inner wall of the needle body channel 12. The rope connected to the end of the needle will be connected to the push button along the needle body channel, the transverse channel, the oblique channel and the annular channel. The surface of the uterine support frame 2 is equipped with a push button 8. One end of the push button 8 is connected to a rope 9. The rope 9 passes through the annular channel 5 and the bending channel 6 and is connected to the end of the elastic electrode needle 7.

[0022] The push-button 8 includes a ring piece 17 disposed in the annular channel 5, as shown in the attached figure. Figure 5 As shown, the ring 17 has a button body 18, and the two ends of the button body 18 have elastic strips 19, and the ends of the elastic strips 19 have arc-shaped blocks 20; the surface of the uterine support 2 has a transverse groove 21, and the two ends of the transverse groove 21 have arc-shaped grooves 22 that cooperate with the arc-shaped blocks 20. In the initial state, the arc-shaped blocks at the ends of the elastic strips away from the uterine support cup are engaged with the corresponding arc-shaped grooves. At this time, the spring is deformed by the limiting protrusion and the limiting ring on the inner wall of the needle channel, and the needle is retracted in the needle channel. If the needle extends out, it pushes the button body, so that the arc-shaped blocks at the ends of the elastic strips near the uterine support cup are engaged with the corresponding arc-shaped grooves. The needle extends out and pierces the cervix under the action of the spring. The upper end of the button body 18 has a thin sheet 23 with an anti-slip layer. When the button body is pushed, pressing the thin sheet can improve the stability and convenience of the button body movement.

[0023] When using the electrode needle at the edge of the uterine cup, this invention only requires rotating the uterine cup 180° to sever the uterine body, reducing the risk of damage to nearby organs by the electro-cutting equipment. Moreover, the vaginal stump is hemostatic due to electro-cutting, reducing local bleeding.

[0024] The working principle of this utility model is as follows: The elastic electrode needle 7 is hidden inside the needle channel 12 of the uterine cup 3. The spring 16 is compressed by the limiting protrusion 15 and the limiting ring, and the needle tip 14 is not exposed. The operator pushes the push button 8 on the surface of the uterine cup 2 with one hand. The button body 18 drives the rope 9 to move towards the uterine cup 3 through the ring plate 17. The rope 9 pulls the needle tip 14 of the elastic electrode needle 7 through the oblique channel 11 and the axial channel 10. Under the action of the spring 16 on the elastic electrode needle 7, The needle 14 extends obliquely along the needle channel 12 to the edge of the uterine cup 3, and the needle 14 penetrates into the cervical tissue. The elastic electrode needle 7 is energized, and the operator rotates the uterine cup 3, which drives the elastic electrode needle 7, which has penetrated into the cervix, to form a circular cutting path along the edge of the cup. The uterine body is severed by the thermal effect of the current. After the cutting is completed, the button body 18 is pushed in the opposite direction, and the arc-shaped block at the end of the elastic strip 19 disengages from the arc-shaped groove 22 near the uterine cup 3 and returns to the initial state. The uterine body falls into the uterine cup 3.
