Description

Technical Field

[0001] The utility model relates to a medical device, in particular to a temperature-adjustable handheld puncture device. Background Art

[0002] A trocar is a surgical needle that replaces a mechanical scalpel for tissue cutting and puncture and is widely used in surgeries involving puncturing the skin and flesh.

[0003] Current treatments for renal cysts include laparoscopic renal cyst decompression and ultrasound-guided percutaneous renal cyst puncture and sclerotherapy. Laparoscopic surgery generally requires three puncture channels: one for laparoscopic observation and two for instrument manipulation. Ultrasound-guided percutaneous renal cyst puncture and sclerotherapy, unlike laparoscopic surgery, only requires one puncture channel. However, because the cyst wall is not removed, there is a certain risk of recurrence. Therefore, laparoscopic renal cyst decompression is currently the most commonly used treatment.

[0004] A paracentesis device is a commonly used surgical instrument in paracentesis procedures, primarily used to establish artificial pneumoperitoneum and provide access for instruments during laparoscopic surgery. Artificial pneumoperitoneum is crucial for successful laparoscopic surgery. It must be established before surgery to separate the peritoneal wall from the internal organs, facilitating surgical access.

[0005] Existing abdominal puncture devices mainly consist of three parts: a puncture needle, a sealing valve, and a puncture sheath. When in use, the puncture needle, sealing valve, and puncture sheath are generally combined first. The puncture needle is used to puncture the puncture sheath through the human skin into the abdominal cavity, and artificial pneumoperitoneum is established through the air injection valve on the puncture sheath. After the puncture needle is removed, the sealing valve and puncture sheath form a surgical channel. The surgical instruments are inserted into the abdominal cavity through the sealing valve and puncture sheath to perform laparoscopic surgery. During the operation, the surgical instruments and the sealing valve are sealed together to ensure that the pneumoperitoneum will not leak and affect the surgical operation. When the lesion tissue needs to be removed, the sealing valve is removed from the puncture sheath, and the retrieval valve on the puncture sheath is used to achieve sealing. The lesion tissue is then removed by using instruments such as biopsy forceps through the retrieval valve.

[0006] In the current prior art, a Chinese patent with authorization publication number CN209996437U discloses an abdominal puncture device, in which an outer tube, an inner tube, and a puncture needle cooperate to achieve abdominal puncture, and then form a laparoscopic surgical operation channel after the puncture needle is removed.

[0007] However, the above technical solution has at least the following defects: the above puncture device cannot seal the bleeding point after puncturing the skin and flesh, and the puncture site is prone to bleeding during the patient's operation.

[0008] For example, a Chinese patent with authorization publication number CN219331898U discloses a puncture card for laparoscopy, which includes a puncture device and a puncture tube sleeve. By providing a thermocoagulation structure at one end of the puncture tube sleeve near the puncture part, the thermocoagulation structure can generate high temperature and directly act on the bleeding point deep in the puncture hole, vaporizing the internal and external fluids of the cells around the wound, causing the cells to shrink and coagulate, sealing the blood vessel wall to stop bleeding.

[0009] However, the above technical solution has at least the following drawbacks: although the above trocar can be heated to stop bleeding, it can only be heated to stop bleeding through the puncture tube sleeve, which has a large limitation in use. In view of this, it is necessary to improve the technology. Summary of the Invention

[0010] The utility model provides a temperature-adjustable handheld puncture device, which is used to seal the bleeding point at the puncture site of the patient and further stop bleeding at the puncture site.

[0011] To achieve the above-mentioned purpose, the technical solution of the present invention is: a handheld puncture device with adjustable temperature, comprising a gripping structure and a puncture structure installed on the gripping structure, a power supply assembly being installed on the gripping structure, the gripping structure comprising a gripping handle, and a mounting hole being opened on one end wall of the gripping handle, the puncture structure being installed at the mounting hole of the gripping structure and being electrically connected to the power supply assembly.

[0012] As a further improvement, a accommodating cavity is formed inside the gripping handle to accommodate the power supply of the power supply component. A USB charging port, a display screen and a control switch module are provided on the outer wall of the gripping handle. The USB charging port, display screen and control switch module are electrically connected to the power supply and form a control circuit of the power supply component.

[0013] As a further improvement, the control switch module is provided with a switch button and a temperature adjustment button, and the temperature adjustment button on the control switch module can adjust the temperature range from 40°C to 80°C.

[0014] As a further improvement, the puncture structure includes a heating core and a puncture guide needle arranged around the heating core. The heating core passes through the mounting hole of the holding structure and is electrically connected to the power supply of the power supply component, so that the current generated by the power supply of the power supply component heats the heating core and transfers the heat to the puncture guide needle around the heating core.

[0015] As a further improvement, the guide needle is wrapped around the periphery of the heating core, and one end of the guide needle is formed with a puncture head for puncturing the patient's skin and flesh, and the other end of the guide needle is formed with a mounting end, which is placed in the mounting hole of the end wall of the gripping handle.

[0016] As a further improvement, a card slot is provided on the outer peripheral surface of the mounting end, and a plurality of elastic card protrusions are provided on the hole wall of the mounting hole, and the plurality of elastic card protrusions are clipped into the card slot of the mounting end.

[0017] As a further improvement, the puncture guide needle is made of 304 medical grade stainless steel.

[0018] As a further improvement, the outer diameter of the puncture guide needle is 5 mm to 15 mm, preferably 10 mm.

[0019] As a further improvement, a plurality of the elastic retaining protrusions are formed in a circular array on the hole wall of the mounting hole with the hole center of the mounting hole (102) as the center. Preferably, the number of the elastic retaining protrusions is six.

[0020] As a further improvement, a plurality of gripping grooves are formed on the outer peripheral wall of the gripping handle.

[0021] The above technical solution of the present invention has the following beneficial effects: the practical handheld puncture device with adjustable temperature heats the puncture structure through the current generated by the power supply component, so that the temperature difference between the front and rear ends of the puncture guide needle is equal and maintains a constant temperature, which can char the patient's puncture port, seal the bleeding point, and achieve hemostasis at the puncture site.

[0030] The following describes the implementation of the present invention in detail with reference to the accompanying drawings and examples.

[0031] See also Figures 1 to 7 As shown, the present invention discloses a temperature-adjustable handheld puncture device, which includes a gripping structure 10, a power supply assembly 30 disposed on the gripping structure 10, and a puncture structure 20 mounted on the gripping structure 10 and electrically connected to the power supply assembly 30.

[0032] Please refer to Figure 2 as well as Figure 3 As shown, the gripping structure 10 includes a gripping handle 101, and a mounting hole 102 is provided on one end wall of the gripping handle 101 for connecting and mounting the puncture structure 20. A plurality of elastic holding protrusions 103 are provided on the hole wall of the mounting hole 102 to clamp and fix the puncture structure 20. Figure 4 As shown, each elastic retaining protrusion 103 includes a connecting section 106 and a retaining section 105 formed on the connecting section 106. One end of the connecting section 106 is formed on the wall of the mounting hole 102, and the other end of the connecting section 106 is formed with the retaining section 105. The top surface of the retaining section 105 forms a retaining surface of a concave cavity for cooperating with and retaining the puncture structure 20, thereby increasing the friction force of the puncture structure 20 within the mounting hole 102. In this embodiment, a plurality of elastic retaining protrusions 103 are formed in an annular array on the wall of the mounting hole 102 with the center of the mounting hole 102 as the center. Preferably, there are six elastic retaining protrusions 103.

[0033] Please refer to Figure 1 As shown, a plurality of gripping grooves 104 are formed on the outer peripheral wall of the gripping handle 101 to facilitate the medical staff to grip and use the trocar.

[0034] Please refer to Figure 2 as well as Figure 7 As shown, a accommodating cavity is formed inside the gripping handle 101 for accommodating the power supply 300 of the power supply assembly 30. In this embodiment, the power supply 300 of the power supply assembly 30 is a lithium battery pack. A USB charging port 301, a display screen 302 and a control switch module 303 are provided on the outer wall of the gripping handle 101. The USB charging port 301, the display screen 302 and the control switch module 303 are electrically connected to the power supply 300 and form a control circuit of the power supply assembly 30.

[0035] Please refer to Figure 1 、 Figures 5 to 7As shown, the puncture structure 20 is installed on the mounting hole 102 of the holding structure 10 and is electrically connected to the power supply assembly 30, so that the power supply assembly 30 is controlled by the control switch module 303 to heat the puncture structure 20, so that the temperature difference between the front and rear ends of the puncture structure 20 is equal, reaching a constant temperature state. After puncturing the skin and flesh, the puncture port can be charred to seal the bleeding point, thereby achieving hemostasis at the puncture site during the patient's surgery.

[0036] The control switch module 303 is provided with a switch button and a temperature adjustment button. In this embodiment, the temperature adjustment button on the control switch module 303 can adjust the temperature range from 40°C to 80°C, so that the puncture structure 20 reaches the corresponding adjusted temperature and displays the temperature through the display screen 302 to adapt to the surgical status of different patients.

[0037] It should be understood that the heating temperature of 40°C to 80°C described in the present invention can be divided into a low temperature range (40-50°C) and a medium-high temperature range (50-80°C). For the low temperature range (40-50°C), heating within this temperature range may not be sufficient to quickly stop bleeding directly through the thermal coagulation effect, especially for bleeding from larger blood vessels. However, for capillary bleeding, appropriate heating may help accelerate the coagulation reaction, because the coagulation process is an enzymatic reaction, and the appropriate temperature can accelerate the rate of thrombin reaction, thereby promoting coagulation. For the medium-high temperature range (50-80°C), when the temperature reaches above 50°C, proteins begin to undergo thermal denaturation, including proteins in the blood and proteins on the blood vessel walls. Thermal denaturation will cause the solubility of proteins to decrease and coagulate, which may fill small capillaries and achieve the effect of stopping bleeding. However, this temperature range is also close to or exceeds the thermal damage threshold of certain tissues (such as the thermal damage threshold of burn professionals is 42°C). Therefore, extreme caution must be taken when using it to avoid causing unnecessary damage to surrounding tissues.

[0038] It should be further understood that the heating temperature of 40°C to 80°C described in the present invention is the operating temperature considered under general circumstances. In actual specific operations, the required temperature needs to be specifically determined according to actual conditions. The specific working principles related to temperature use are existing technologies, so they will not be described in detail in this article. For example, you can refer to the Chinese patent with authorization announcement number CN219331898U, which discloses a laparoscope stamp card.

[0039] For details, please refer to Figure 5 as well as Figure 6As shown, the puncture structure 20 includes a heating core 201 and a puncture guide needle 202 arranged on the periphery of the heating core 201. The heating core 201 passes through the mounting hole 102 of the holding structure 10 and is electrically connected to the power supply of the power supply component 30. The current generated by the power supply of the power supply component 30 heats the heating core 201 and transfers the heat to the puncture guide needle 202 on the periphery of the heating core 201, so that the temperature difference between the front and rear ends of the puncture guide needle 202 is equivalent and a constant temperature is maintained.

[0040] It should be understood that the working principle of heating a metal puncture device by power supply to stop bleeding is a prior art, so it will not be described in detail in this article. For example, you can refer to a laparoscope stamp card disclosed in Chinese patent authorization announcement number CN219331898U.

[0041] Further references Figure 5 As shown, the puncture guide needle 202 is wrapped around the outer periphery of the heating core 201. One end of the puncture guide needle 202 forms a puncture head 2021, and the other end forms a mounting end 2022. The outer periphery of the mounting end 2022 is provided with a retaining groove 2023. The mounting end 2022 of the puncture guide needle 202 is placed in the mounting hole 102 of the end wall of the gripping handle 101, and the elastic retaining protrusion 103 is engaged with the retaining groove 2023 of the mounting end 2022. The puncture head 2021 at one end of the puncture guide needle 202 is used to puncture the patient's skin. In this embodiment, the puncture guide needle 202 is made of 304 medical-grade stainless steel and has an outer diameter of 5 mm to 15 mm, preferably 10 mm.

[0042] During use, the medical staff places their fingers on the gripping groove 104 on the peripheral wall of the gripping handle 101, holds the main body of the gripping handle 101 with their palms, and places their thumbs on the control switch module 303 on the peripheral wall of the gripping handle 101 to insert the puncture head 2021 at one end of the puncture guide needle 202 in the puncture structure 20 into the skin of the patient undergoing surgery. After completion, the medical staff presses the control switch module 303 on the peripheral wall of the gripping handle 101 with their thumbs, turns on the switch button, and then presses the temperature adjustment button to heat the heating core 201 of the puncture structure 20 through the current generated by the power supply component 30, and transfers the heat of the heating core 201 to the peripheral area of ​​the heating core 201. On the puncture guide needle 202, the temperature difference between the front and rear ends of the puncture guide needle 202 is equal, reaching a constant temperature state. During the patient's operation, after the puncture guide needle 202 punctures the skin and flesh through the puncture head 2021 at one end, when the puncture guide needle 202 is taken out, the patient's puncture port can be charred to seal the bleeding point, achieve hemostasis at the puncture site, and separate and coagulate the body tissue, thereby achieving the purpose of puncture and hemostasis. At the same time, the puncture port edge can be automatically disinfected, and the temperature of the puncture structure 20 can be adjusted accordingly by controlling the temperature adjustment button on the switch module 303, and the temperature can be displayed on the display screen 302 to adapt to the surgical status of different patients.

[0043] It should be understood that in the present invention, the mechanical structure and working principle of the heating core 201 are all existing technologies, so they will not be described in detail in this article. The types of heating core 201 that can be used include but are not limited to ferrite heating cores, nickel-chromium alloy heating cores, PTC heating cores, sleeve-type electric heating cores, etc.

[0044] Furthermore, in some embodiments of the temperature-adjustable handheld puncture device, a puncture sheath body 40 is further included, and the puncture sheath body 40 and the puncture structure 20 are detachably mounted.

[0045] In these embodiments, Figure 8 As shown, the puncture guide needle 202 passes through the puncture sheath body 40 , and the puncture head 2021 is adapted to the puncture end 401 of the puncture sheath body 40 .

[0046] It should be understood that in the present invention, the detailed mechanical structure and working principle of the puncture sheath body 40 are all existing technologies, so its mechanical structure and working principle will not be described again in this article. You can refer to the abdominal puncture device disclosed in the Chinese patent with authorization announcement number CN209996437U, which has the same working principle as the puncture structure 20 (puncture needle) and the puncture sheath body 40 (outer tube and inner tube) of the present invention.

[0047] It should be further understood that the mechanical structure and working principle of the remaining components related to the puncture device, such as the sealing valve (not shown in detail in the figure), are all existing technologies, so they are not described in detail in this article.

[0048] When using the temperature-adjustable handheld puncture device provided by the present invention, first confirm the location where the patient needs to be punctured (other treatment techniques may be used), then align the handheld puncture device with the location for puncture, and perform the puncture operation through the cooperation of the gripping structure 10, the power supply assembly 30, the puncture structure 20, and the puncture sheath body 40. Then, a laparoscopic surgical operation channel is established through the puncture sheath body 40. The puncture structure 20 is then withdrawn from the puncture sheath body 40 through the gripping structure 10 and replaced with medical instruments such as forceps and a laparoscope for surgical operation. When it is necessary to stop bleeding at the puncture site, the temperature of the puncture guide needle 202 is controlled by the power supply assembly 30 so that the puncture guide needle 202 is heated to an appropriate temperature according to the needs of different patients, and then the bleeding at the puncture site is stopped.

[0049] It should be understood that the mechanical structure and working principle of controlling the puncture guide needle 202 through the power supply component 30 (detailed structure as described above) are all existing technologies, so the detailed mechanical structure and working principle of the power supply component 30, as well as the related mechanical structure and working principle of controlling the temperature will not be described in this article. You can refer to the acupuncture needles used in conjunction with the warm needle and electroacupuncture comprehensive instrument in real life to accurately control the temperature and display the temperature in real time during use to ensure the safety and effectiveness of the treatment.

[0050] In summary, the temperature-adjustable handheld puncture device of the present invention heats the puncture structure 20 through the current generated by the power supply component 30, so that the temperature difference between the front and rear ends of the puncture guide needle 202 is equal and maintained at a constant temperature. The puncture port of the patient can be charred to seal the bleeding point and achieve hemostasis at the puncture site.

[0051] The above-described embodiments are merely preferred embodiments of the present invention and are not intended to limit the scope of the present invention. Without departing from the design spirit of the present invention, various modifications and improvements made to the technical solutions of the present invention by ordinary technicians in this field should fall within the scope of protection determined by the claims of the present invention.
