Description

Technical Field

[0001] The present invention relates to the technical field of medical devices, and in particular to a disposable intelligent bipolar circumcision stapler and a method of using the same. Background Art

[0002] Phimosis or foreskin is one of the main factors affecting male reproductive health. Circumcision is one of the good measures to prevent such diseases. Conventional circumcision surgery requires sutures and staples after completion, which is more complicated to use.

[0003] A circumcision stapler with publication number CN109925027A discloses a structure comprising a shell, at least one firing handle rotatably connected to the shell, and a stop mechanism; wherein, when the stop mechanism is in a first state and the firing handle rotates and abuts the stop mechanism, the angle between the firing handle and the axial direction of the circumcision stapler is a first angle, and when the stop mechanism is in a second state and the firing handle rotates and abuts the stop mechanism, the angle between the firing handle and the axial direction of the circumcision stapler is a second angle, and the first angle is different from the second angle; it discloses a structure that still requires suturing staples after circumcision is completed, which is difficult and complicated to use. Summary of the Invention

[0004] The technical problem to be solved by the present invention is that anastomosis staples are still required after circumcision.

[0005] In order to solve the above technical problems, the present invention adopts the following technical solutions:

[0006] First, a disposable intelligent bipolar foreskin stapler is provided, comprising a shell, a conductive rod passing through the shell, a glans seat installed at one end of the conductive rod, and a knob installed at the other end through a thread, an electrode ring is provided on the side of the shell corresponding to the glans seat, a circumcision blade is provided in the electrode ring, a handle connected to the circumcision blade is provided on the shell, a positive electrode ring is installed at one end of the electrode ring, and a negative electrode sheet connected to the conductive rod is provided at the position of the glans seat corresponding to the positive electrode ring.

[0007] By turning the knob to move the conductive rod, the positive electrode ring and the negative electrode sheet clamp the foreskin, and then the positive electrode ring and the negative electrode sheet are energized to solidify, and then the circular cutting blade is used to cut.

[0008] Furthermore, an annular negative conductive sheet is provided in the shell, the conductive rod passes through the negative conductive sheet, and 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 the switch from being accidentally touched when the foreskin is not clamped, causing an arc to occur between the positive ring and the negative sheet, preventing medical accidents, and making the device more effective.

[0009] Furthermore, a sleeve is provided in the shell and is sleeved on the conductive rod. A circular cutting blade is installed at one end of the sleeve, and the handle is connected to the sleeve. The sleeve is used for transmission, so that the use effect of the device is better.

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

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

[0012] Furthermore, an annular pad blade is provided at the position of the glans seat corresponding to the circumcision blade; when the circumcision blade cuts the pad blade, it can ensure that the foreskin is cut off, making the use effect of the device better.

[0013] Furthermore, a button switch connected to the positive electrode ring is provided on the housing; the knob switch is used to ensure that the device can be controlled to be powered on, making it more stable to use.

[0014] The present invention further provides a method for using a stapler, characterized in that it includes the stapler described above, the positive electrode ring and the negative electrode sheet are provided with temperature sensors, and the housing is provided with a radio frequency signal generator connected to the positive electrode ring, comprising the following steps:

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

[0016] S2: Turn the knob to clamp the foreskin tightly with the positive electrode ring and the negative electrode sheet;

[0017] S3: RF signal generator works;

[0018] S4: When the temperature sensor detects the preset temperature, the handle is moved to allow the circumcision blade to cut the foreskin.

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

[0020] S6: Pull out the conductive rod for subsequent processing.

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

[0022] The impedance of biological tissues during the coagulation process shows different performances as the temperature rises. Different biological tissues have different electrical impedance characteristics, but they basically conform to the following: Figure 5 The rules shown.

[0023] Starting from normal body temperature, the electrical impedance of biological tissues shows a downward trend until the temperature reaches about 60°C, and the impedance is minimum at around 60°C; when the temperature rises from 60°C, the impedance of biological tissues tends to rise. During this process, the evaporation of water and protein denaturation inside the tissues are the main reasons for the impedance change. When the temperature rises to 100°C, the cells gradually rupture and form carbonization.

[0024] Vascular coagulation occurs between 60 and 70°C, so it is very important to properly control tissue temperature. Since tissue impedance and temperature are strongly correlated, the system can estimate tissue temperature by real-time detection of tissue impedance, thereby determining the vascular coagulation effect and intelligently determining when the system should stop.

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

[0026] The present invention has the following beneficial effects: the present invention utilizes a positive electrode ring and a negative electrode sheet to clamp the foreskin, and applies electricity to coagulate it, so that the wound can heal more quickly after cutting. Since the cutting is performed after coagulation, no suturing or staples are required after cutting, which reduces the surgical steps and prevents the patient from being hurt again, resulting in a better surgical effect. At the same time, by observing the blade pad, it can be determined whether the foreskin is cut, making the use effect of the device more obvious, safer and more stable. At the same time, the use method of the stapler provided by the present invention determines that the cutting effect can be better within a suitable temperature, and the patient suffers less pain.

Those skilled in the art will be able to understand the specific meanings of the above terms in the present invention based on specific circumstances.

[0037] The present invention provides a disposable intelligent bipolar foreskin stapler, such as Figure 1 and Figure 2 As shown, it includes a shell 10, wherein a conductive rod 20 is passed through the shell 10, wherein a glans seat 21 is installed at one end of the conductive rod 20, and a knob 22 is installed at the other end through a thread, an electrode ring 11 is provided at a position corresponding to the glans seat 21 on the shell 10, and a circumcision blade 12 is provided in the electrode ring 11, and a handle 18 is installed on the shell 10, and the handle 18 is connected to the circumcision blade 12 for pushing the circumcision blade 12 to move for cutting.

[0038] like Figure 2 and Figure 4As shown, during use, the device first wraps the excess foreskin 30 on the glans seat 21, then turns the knob 22 to move the conductive rod 20, thereby moving the glans seat 21 closer to the electrode ring 11 until the glans seat 21 and the electrode ring 11 clamp the foreskin 30, and then operates the handle 18 to move the circumcision blade 12 to cut the foreskin 30.

[0039] like Figure 2 As shown, in order to achieve better surgical effects, in this embodiment, a positive electrode ring 13 is installed at one end of the electrode ring 11 close to the glans seat 21, and a negative electrode sheet 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 sheet 23, wherein 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 sheet 23, thereby coagulating the foreskin 30, which is convenient for the circumcision blade 12 to cut and ensures that the wound heals more quickly after the operation without the need for additional sutures and staples.

[0040] like Figure 2 As shown, in this embodiment, an annular negative conductive sheet 24 is provided in the housing 10, and the conductive rod 20 passes through the negative conductive sheet 24, wherein a step 25 is provided at the position of the conductive rod 20 corresponding to the negative conductive sheet 24. When the conductive rod 20 is inserted into the housing 10, the step 25 first does not contact the negative conductive sheet 24. Then, the knob 22 is turned to clamp the foreskin 30 with the positive ring 13 and the negative sheet 23. Only then will the step 25 contact the negative conductive sheet 24, and only then will the conductive rod 20 be energized.

[0041] like Figure 2 and Figure 3 As shown, a sleeve 15 is provided in the outer shell 10 and is sleeved on the conductive rod 20. A circular cutting blade 12 is installed at one end of the sleeve 15. The sleeve 15 is connected to the handle 18. The sleeve 15 can be driven to move by turning the handle 18, and the circular cutting blade 12 can be driven to move. A reset spring 16 is provided between the sleeve 15 and the outer shell 10. When the handle 18 is released, the circular cutting blade 12 is reset under the action of the reset spring 16.

[0042] At the same time, in order to make the device more stable, a guide groove 17 is provided on the inner side of the sleeve 15, and an adaptive guide block 26 is provided at the position of the conductive rod 20 corresponding to the guide groove 17 to ensure that the conductive rod 20 moves more smoothly when the knob 22 is turned, preventing the conductive rod 20 from rotating relative to the sleeve 15, making the device more stable to use.

[0043] like Figure 4As shown, an annular pad blade 27 is provided on the glans seat 21 at a position corresponding to the circumcision blade 12. During the operation, the circumcision blade 12 is required to cut the pad blade 27 to ensure that the foreskin 30 is cut smoothly.

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

[0045] The impedance of biological tissues during the coagulation process shows different performances as the temperature rises. Different biological tissues have different electrical impedance characteristics, but they basically conform to the following: Figure 5 The rules shown.

[0046] Starting from normal body temperature, the electrical impedance of biological tissues shows a downward trend until the temperature reaches about 60°C, and the impedance is minimum at around 60°C; when the temperature rises from 60°C, the impedance of biological tissues tends to rise. During this process, the evaporation of water and protein denaturation inside the tissues are the main reasons for the impedance change. When the temperature rises to 100°C, the cells gradually rupture and form carbonization.

[0047] Vascular coagulation occurs between 60 and 70°C, so it is very important to properly control tissue temperature. Since tissue impedance and temperature are strongly correlated, the system can estimate tissue temperature by real-time detection of tissue impedance, thereby determining the vascular coagulation effect and intelligently determining when the system should stop.

[0048] So the use steps of the present invention are as follows:

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

[0050] S2: Turn the knob 22 to clamp the foreskin 30 with the positive electrode ring 13 and the negative electrode sheet 23;

[0051] S3: RF signal generator works;

[0052] S4: When the temperature sensor detects that the temperature reaches 60-70° C., the handle 18 is moved to allow the circumcision blade 12 to cut the foreskin 30 .

[0053] S5: Release the handle 18, and then rotate the knob 22 in the opposite direction until it is separated from the conductive rod 20.

[0054] S6: Pull out the conductive rod 20 for subsequent processing.
