Description

Disposable intelligent bipolar circumcision stapler and its usage method Technical Field

[0001] This invention relates to the field of medical device technology, specifically to a disposable intelligent bipolar circumcision stapler and its usage method. Background Technology

[0002] Phimosis or paraphimosis is one of the main factors affecting male reproductive health. Circumcision is one of the best measures to prevent these diseases. Conventional circumcision surgery requires suturing staples after the procedure, which is relatively complicated.

[0003] A circumcision stapler with publication number CN109925027A discloses a device including a housing, at least one firing handle rotatably connected to the housing, and a stop mechanism. When the stop mechanism is in a first state and the firing handle rotates and abuts against the stop mechanism, the angle between the firing handle and the axial direction of the circumcision stapler is a first angle. When the stop mechanism is in a second state and the firing handle rotates and abuts against the stop mechanism, the angle between the firing handle and the axial direction of the circumcision stapler is a second angle. The first angle and the second angle are different. This device discloses a structure that still requires suturing staples after circumcision, making it difficult and complex to use. Summary of the Invention

[0004] The technical problem to be solved by this invention is the need to suture the anastomotic staples after circumcision.

[0005] To solve the above-mentioned technical problems, the present invention adopts the following technical solution:

[0006] First, a disposable intelligent bipolar circumcision stapler is provided, including a housing. A conductive rod is inserted inside the housing. A glans seat is installed at one end of the conductive rod, and a knob is installed at the other end via a thread. An electrode ring is provided on the side of the housing corresponding to the glans seat. A circumcision blade is installed inside the electrode ring. A handle connected to the circumcision blade is provided on the housing. A positive electrode ring is installed at one end of the electrode ring. A negative electrode plate communicating with the conductive rod is provided at the position of the glans seat corresponding to the positive electrode ring.

[0007] By rotating the knob, the conductive rod is moved, causing the positive electrode ring and negative electrode plate to clamp the sheath. Then, the positive electrode ring and negative electrode plate are energized to seal them, and then the ring-cutting blade is used to cut them.

[0008] Furthermore, an annular negative conductive sheet is provided inside the outer casing, and the conductive rod passes through the negative conductive sheet. A step is provided at the position of the conductive rod corresponding to the negative conductive sheet. The step and the negative conductive sheet enable the conductive rod to be energized smoothly, thereby preventing accidental activation of the switch when the foreskin is not clamped tightly, which could cause an electric arc between the positive and negative electrodes, thus preventing medical accidents and improving the effectiveness of the device.

[0009] Furthermore, a sleeve is provided inside the outer shell and fitted onto the conductive rod. A circumferential cutting blade is installed at one end of the sleeve, and the handle is connected to the sleeve. The use of the sleeve for transmission improves the effectiveness of the device.

[0010] Furthermore, a guide groove is provided inside the sleeve, and a guide block is provided at the position of the conductive rod corresponding to the guide groove; the guide groove and guide block are used to prevent the conductive rod from rotating, ensuring that the device is more stable during use.

[0011] Furthermore, a return spring is provided between the sleeve and the outer shell; the return spring is used to return the sleeve to its original position, thereby separating the circumferential cutting blade from the glans seat.

[0012] Furthermore, an annular pad blade is provided at the position of the glans seat corresponding to the circumferential cutting blade; when the circumferential cutting blade cuts the pad blade, it can ensure that the foreskin is cut off, thus improving the effectiveness of this device.

[0013] Furthermore, a push-button switch connected to the positive electrode ring is provided on the outer casing; the rotary switch ensures that the device can be powered on manually, making its use more stable.

[0014] The present invention also provides a method of using a stapler, characterized in that it includes the stapler as described above, wherein temperature sensors are disposed on the positive electrode ring and the negative electrode plate, and a radio frequency signal generator connected to the positive electrode ring is disposed inside the housing, comprising the following steps:

[0015] S1: Wrap the foreskin around the glans;

[0016] S2: Turn the knob to clamp the foreskin between the positive electrode ring and the negative electrode plate;

[0017] S3: Radio frequency signal generator is working;

[0018] S4: When the temperature sensor detects the preset temperature, move the handle to make the circumcision blade cut the foreskin.

[0019] S5: Release the handle, then turn the knob in the opposite direction until it separates from the conductive rod.

[0020] S6: Remove the conductive rod for further processing.

[0021] Furthermore, the radio frequency signal generator has a frequency range of 300kHz to 1000kHz and a peak-to-peak voltage range of ±200V to ±600V.

[0022] During the solidification process, the impedance of biological tissues exhibits different characteristics as the temperature increases. Different biological tissues have different electrical impedance characteristics, but they generally conform to the pattern shown in Figure 5.

[0023] From normal body temperature up to about 60°C, the electrical impedance of biological tissues tends to decrease, reaching its minimum at around 60°C. As the temperature rises from 60°C, the impedance of biological tissues tends to increase. During this process, the evaporation of water and the denaturation of proteins within the tissue are the main reasons for the change in impedance. When the temperature rises to 100°C, the cells gradually rupture and form carbon.

[0024] Vascular clotting occurs between 60 and 70°C. Therefore, proper control of tissue temperature is crucial. Since tissue impedance and temperature are strongly correlated, the system can estimate tissue temperature by detecting tissue impedance in real time, thereby determining the vascular clotting effect and enabling intelligent judgment of when to stop the system.

[0025] Furthermore, the preset temperature in S4 is 60-70°C.

[0026] The present invention has the following beneficial effects: By using a positive electrode ring and a negative electrode plate to clamp the foreskin and applying electricity to coagulate it, the wound can heal more quickly after cutting. Since the cutting is done after coagulation, there is no need to suture the anastomosis staples after cutting, reducing surgical steps and preventing further injury to the patient, resulting in better surgical outcomes. At the same time, by observing the shim blade, it can be determined whether the foreskin has been cut, making the use of this device more effective, safer, and more stable. In addition, the method of using the anastomosis device provided by the present invention ensures that the cutting effect is better and the patient suffers less pain within a suitable temperature range.

Thus, a feature defined as "first" or "second" may explicitly or implicitly include at least one of that feature. In the description of this invention, "a plurality of" means at least two, such as two, three, etc., unless otherwise explicitly specified.

[0036] In this invention, unless otherwise explicitly specified and limited, the terms "connection," "fixed," etc., should be interpreted broadly. For example, "fixed" can mean a fixed connection, a detachable connection, or an integral part; it can mean a mechanical connection or an electrical connection; it can mean a direct connection or an indirect connection through an intermediate medium; it can mean the internal communication of two components or the interaction between two components, unless otherwise explicitly limited. Those skilled in the art can understand the specific meaning of the above terms in this invention according to the specific circumstances.

[0037] This invention provides a disposable intelligent bipolar circumcision stapler, as shown in Figures 1 and 2. It includes a housing 10, on which a conductive rod 20 is threaded. One end of the conductive rod 20 is fitted with a glans seat 21, and the other end is threaded with a knob 22. An electrode ring 11 is provided on the housing 10 at a position corresponding to the glans seat 21. A circumcision blade 12 is provided inside the electrode ring 11. A handle 18 is installed on the housing 10 and is connected to the circumcision blade 12 for pushing the circumcision blade 12 to move and cut.

[0038] As shown in Figures 2 and 4, during the use of this device, the excess foreskin 30 is first wrapped around the glans seat 21. Then, the knob 22 is turned to move the conductive rod 20, thereby bringing the glans seat 21 closer to the electrode ring 11 until the glans seat 21 and the electrode ring 11 clamp the foreskin 30. Then, the handle 18 is operated to move the ring cutting blade 12 to cut the foreskin 30.

[0039] As shown in Figure 2, in order to improve the surgical effect, in this embodiment, a positive electrode ring 13 is installed at the end of the electrode ring 11 near the glans seat 21, and a negative electrode plate 23 connected to the conductive rod 20 is installed at the position of the glans seat 21 corresponding to the positive electrode ring 13. During use, the foreskin 30 is clamped by the positive electrode ring 13 and the negative electrode plate 23. A button switch 14 is provided on the outer shell 10. Pressing the button switch 14 energizes the positive electrode ring 13 and the negative electrode plate 23, thereby enabling the foreskin 30 to be coagulated. This facilitates the cutting of the circumcision blade 12 and ensures faster wound healing after surgery, without the need for additional suture staples.

[0040] As shown in Figure 2, in this embodiment, an annular negative electrode conductive sheet 24 is provided inside the outer shell 10, and a conductive rod 20 passes through the negative electrode conductive sheet 24. A step 25 is provided at the position of the conductive rod 20 corresponding to the position of the negative electrode conductive sheet 24. When the conductive rod 20 is inserted into the outer shell 10, the step 25 does not contact the negative electrode conductive sheet 24 at first. Then, after rotating the knob 22 to clamp the outer shell 30 with the positive electrode ring 13 and the negative electrode sheet 23, the step 25 will contact the negative electrode conductive sheet 24, and the conductive rod 20 will be energized.

[0041] As shown in Figures 2 and 3, a sleeve 15 is provided inside the outer shell 10 and is fitted onto the conductive rod 20. A ring-cutting blade 12 is installed at one end of the sleeve 15. The sleeve 15 is connected to a handle 18. Moving the handle 18 will move the sleeve 15, which in turn will move the ring-cutting blade 12. A return spring 16 is provided between the sleeve 15 and the outer shell 10. When the handle 18 is released, the ring-cutting blade 12 is reset by the action of the return spring 16.

[0042] Meanwhile, to make the device more stable, a guide groove 17 is provided on the inner side of the sleeve 15, and a matching guide block 26 is provided at the position of the conductive rod 20 corresponding to the guide groove 17, so as to ensure that the conductive rod 20 moves more smoothly when the knob 22 is turned, and to prevent the conductive rod 20 from rotating relative to the sleeve 15, making the device more stable to use.

[0043] As shown in Figure 4, a ring-shaped pad blade 27 is provided on the glans seat 21 at the position corresponding to the ring cutting blade 12. During the operation, the ring cutting blade 12 needs to cut the pad blade 27 to ensure that the foreskin 30 is cut off smoothly.

[0044] The present invention also provides a method of using a stapler, as shown in Figures 1-5, including the stapler as described above, wherein temperature sensors are provided on the positive electrode ring 13 and the negative electrode plate 23, and a radio frequency signal generator connected to the positive electrode ring 13 is provided inside the housing 10, wherein the radio frequency signal generator has a frequency range of 300kHz to 1000kHz and a peak-to-peak voltage range of ±200V to ±600V.

[0045] During the solidification process, the impedance of biological tissues exhibits different characteristics as the temperature increases. Different biological tissues have different electrical impedance characteristics, but they generally conform to the pattern shown in Figure 5.

[0046] From normal body temperature up to about 60°C, the electrical impedance of biological tissues tends to decrease, reaching its minimum at around 60°C. As the temperature rises from 60°C, the impedance of biological tissues tends to increase. During this process, the evaporation of water and the denaturation of proteins within the tissue are the main reasons for the change in impedance. When the temperature rises to 100°C, the cells gradually rupture and form carbon.

[0047] Vascular clotting occurs between 60 and 70°C. Therefore, proper control of tissue temperature is crucial. Since tissue impedance and temperature are strongly correlated, the system can estimate tissue temperature by detecting tissue impedance in real time, thereby determining the vascular clotting effect and enabling intelligent judgment of when to stop the system.

[0048] Therefore, the steps for using this invention are as follows:

[0049] S1: Wrap the foreskin 30 around the glans penis seat 21;

[0050] S2: Rotate knob 22 to clamp the outer sheath 30 between the positive electrode ring 13 and the negative electrode plate 23;

[0051] S3: Radio frequency signal generator is working;

[0052] S4: When the temperature sensor detects that the temperature reaches 60-70℃, move the handle 18 so that the circumcision blade 12 cuts the foreskin 30.

[0053] S5: Release handle 18, then turn knob 22 in the opposite direction until it separates from conductive rod 20.

[0054] S6: Remove the conductive rod 20 for further processing.

[0055] It should be understood that the above description of specific embodiments of the present invention is only for illustrating the technical approach and features of the present invention, and is intended to enable those skilled in the art to understand the content of the present invention and implement it accordingly. However, the present invention is not limited to the specific embodiments described above.
