Description

Technical Field

[0001] This invention relates to the field of medical devices, and more particularly to a peritoneal perfusion chemotherapy puncture device. Background Technology

[0002] Hyperthermic intraperitoneal chemotherapy (HIPEC) is a special form of chemotherapy in which a liquid containing chemotherapy drugs is heated to a specific temperature and then infused into the patient's peritoneal cavity, where it is maintained for a period of time. This treatment aims to enhance the efficacy of chemotherapy drugs through high temperatures, while also directly targeting tumor cells to kill tumor cells and micro-lesions.

[0003] Currently, in intraperitoneal hyperthermic perfusion chemotherapy, three to four tubes are typically placed in the patient's body, including inlet and outlet tubes to maintain circulation. The inlet and outlet of these tubes are compressed by abdominal tissues, affecting the inflow and outflow of fluids. Therefore, adjustments to the tubes (including pulling and rotating) are necessary. When medical staff pull the tubes, it can affect the patient's surgical site; when they twist the tubes, the force applied can cause the tubes to become kinked or blocked inside the abdominal cavity.

[0018] To make the technical problems, technical solutions, and beneficial effects of the present invention clearer, the present invention will be further described in detail below with reference to the accompanying drawings and embodiments.

[0019] like Figures 1 to 5 As shown, this embodiment discloses a peritoneal perfusion chemotherapy puncture device, including a front puncture tube body 1, a support guide wire 201, a handle 3, and a guide seat 4.

[0020] The anterior puncture tube 1 has multiple guide wire channels 2 arranged in a ring in the tube wall. Each guide wire channel 2 extends along the length of the anterior puncture tube 1, and the tail end of each guide wire channel 2 extends to the outer wall of the rear of the anterior puncture tube 1. A support guide wire 201 is inserted into the guide wire channel 2, and the rear end of the support guide wire 201 is inserted and fixed to the handle 3.

[0021] The guide seat 4 is fixed at the blade. The guide seat 4 includes a guide head 401 with open ends. A support plate 402 is provided on the outer wall of the guide head 401. The support plate 402 is fixed on the skin. An annular groove 403 is provided on the inner wall of the guide head 401. An inflation ring 404 is provided in the annular groove 403. The inflation ring 404 is connected to an inflation pipe 405 provided on the outer wall of the guide head 401.

[0022] Usage of this invention: The guide head 401 is fitted onto the front puncture tube 1, and the rear end of the front puncture tube 1 is connected to the rear tube 7, which is then connected to the instrument. The support plate 402 is fixed to the skin at the incision site, and the lower end of the guide head 401 is inserted into the incision. Gauze can be used to fill the area around the incision to stop bleeding.

[0023] First, multiple guidewire channels 2 are arranged in the wall of the anterior puncture tube 1. Depending on the surgical needs, a support guidewire 201 is inserted into one or more guidewire channels 2 to support the anterior puncture tube 1. The length of the inserted support guidewire 201 can be changed and adjusted to adjust the support position of the anterior puncture tube 1. The support guidewire 201 is usually made of metal and has a certain degree of flexibility and rigidity. After the support guidewire 201 is inserted into the guidewire channel 2, it acts as a support rib in the anterior puncture tube 1. Rotating the operating handle 3 at the tail end of the anterior puncture tube 1 facilitates a certain degree of rotation of the anterior puncture tube 1, thereby adjusting the orientation of the front end of the anterior puncture tube 1.

[0024] Furthermore, since the rotation and pulling operations of the anterior puncture tube 1 are all performed in the guide seat 4, direct contact between the anterior puncture tube 1 and the incision site is avoided, reducing patient discomfort. The inflation ring 404 in the guide seat 4 acts as a seal, preventing fluid in the abdominal cavity from flowing out of the guide head 401. At the same time, the inflation ring 404 can tighten the anterior puncture tube 1, fixing it in place without external force. The tightening force of the inflation ring 404 on the anterior puncture tube 1 can be adjusted through the inflation pipe 405, which is connected to the inflation / deflation device.

[0025] In this embodiment, the front end of each guidewire channel 2 extends to the front part of the anterior puncture tube 1. The front end of the guidewire channel 2 is a blind hole.

[0026] In this embodiment, the cross-section of each support guide wire 201 is circular, the aperture of the support guide wire 201 is slightly larger than the inner diameter of the guide wire channel 2, and grease can be applied to the outer wall of the support guide wire 201 when it is inserted.

[0027] In this embodiment, a soft rubber sleeve 409 is fixed to the lower end of the guide head 401. The soft rubber sleeve 409 covers the outer wall of the front puncture tube body 1, further improving the sealing performance of the guide head 401 and the front puncture tube body 1.

[0028] In this embodiment, the handle 3 includes a ring 301, which is fixed to the front puncture tube 1. The annular outer wall of the ring 301 is provided with several serrated grooves 303 to improve the friction when the handle 3 is twisted. The ring 301 is provided with multiple insertion holes 302, and a connector 202 is fixed to the rear end of the guide wire 201, which is inserted into the insertion hole 302.

[0029] In this embodiment, a balloon 5 is provided at the front of the anterior puncture tube 1, and the balloon 5 is connected to an inflation channel 501 disposed in the wall of the anterior puncture tube 1. The inflation channel 501 is connected to an inflation / deflation device through an external tube. After the balloon 5 is inflated, it can push away the abdominal tissue at the front of the anterior puncture tube 1.

[0030] In this embodiment, the support plate 402 is fixed to the skin via an adhesive layer 406. The adhesive layer 406 can be an acrylic pressure-sensitive adhesive, which bonds with slight pressure and is less likely to leave residue or damage the skin upon peeling. It is widely used in medical tapes, dressing fixation, and other applications.

[0031] The support plate 402 is a flexible silicone plate. The adhesive layer 406 is provided with release paper 407. The release paper 407 has a tear line 408 in the middle. When in use, the support plate 402 is bent to both sides, which will cause the release paper 407 to break along the tear line 408 in the middle. After the release paper 407 breaks, the break point will be lifted up. The release paper 407 can be torn off along the lifted point.

[0032] like Figure 1 and 6 As shown, the tail end of the front puncture tube 1 is connected to the rear tube 7 via a rotary joint 6. When the front puncture tube 1 rotates, it will not affect the rear tube 7.

[0033] The rotary joint 6 includes a first mating end 601 and a second mating end 602. The first mating end 601 is connected to the rear tube body 7, and the second mating end 602 is connected to the front piercing tube body 1. The first mating end 601 is provided with an insertion interface 603, and the second mating end 602 is provided with an insertion connector 604. The insertion connector 604 and the insertion interface 603 are inserted into each other, and multiple sealing rings 605 are provided between the insertion connector 604 and the insertion interface 603. A cap 606 is provided at the port of the insertion interface 603, and the cap 606 is threadedly connected to the first mating end 601. A rigid retaining ring 607 is provided on the outer wall of the insertion connector 604, and the rigid retaining ring 607 abuts against the cap 606.

[0034] The embodiments described above are merely preferred embodiments of the present invention and are not intended to limit the scope of the present invention. Various modifications and improvements made by those skilled in the art to the technical solutions of the present invention without departing from the spirit of the present invention should fall within the protection scope defined by the claims of the present invention.
