Description

Technical Field

[0001] This utility model relates to the field of medical auxiliary devices, and in particular to a multi-channel integrated stoma dynamic support device. Background Technology

[0002] In intracranial hematoma evacuation surgery, the key to surgical success lies in safely and effectively removing the hematoma while protecting brain tissue.

[0003] As a crucial surgical pathway, the stability and support of the stoma directly impact the procedure and patient prognosis. A suitable stoma support device provides a stable operating space for surgical instruments, reduces damage to surrounding brain tissue, and improves surgical precision and safety. However, with the increasing complexity of intracranial hematoma evacuation surgeries, the requirements for stoma support devices are also becoming more stringent.

[0004] Currently, the shape and size of some devices are fixed and cannot be adjusted according to the specific situation of the patient, resulting in a mismatch with the patient's brain anatomy, which affects the support effect and surgical operation. For example, some devices cannot fit tightly against the cortical stoma, which can easily cause instability in the operating space of surgical instruments and increase surgical risks. To address these issues, a multi-channel integrated stoma dynamic support device is proposed. Utility Model Content

[0005] To overcome the above shortcomings, this utility model provides a multi-channel integrated stoma dynamic support device, which aims to improve the problem that some existing devices cannot fit tightly against the dermal stoma, which easily causes instability in the operating space of surgical instruments and increases surgical risks.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: a multi-channel integrated stoma dynamic support device, including an arc-shaped block, wherein two sets of positioning cylinders are fixedly connected to the inner arc surface of the arc-shaped block, and elastic clamps are provided on the inner sidewall of the positioning cylinders.

[0007] The elastic clamp includes a slot, and a spring sheet is provided on the inner sidewall of the slot.

[0008] As a further description of the above technical solution:

[0009] The empty slots are provided in four sets, and all four sets of empty slots are opened on the inner arc surface of the positioning cylinder.

[0010] As a further description of the above technical solution:

[0011] The positioning cylinder is a through-hole cylindrical tube.

[0012] As a further description of the above technical solution:

[0013] The overall shape of the arc-shaped block is arc-shaped.

[0014] This utility model has the following beneficial effects:

[0015] 1. In this utility model, the arc-shaped block is made of polyetheretherketone (PEEK) material, which can be precisely shaped by heating. It can be adjusted according to the specific anatomical structure of different patients' brains, closely fitting the cortical stoma and surrounding brain tissue, providing a stable space for surgical operation. Its high strength can effectively resist external forces during surgery, maintain the stability of the stoma, and reduce damage to surrounding brain tissue. During the operation, no matter how complex the patient's brain structure is, this device can provide reliable support, ensuring the smooth progress of the operation, improving the accuracy and safety of the operation, and providing a strong guarantee for the patient's treatment effect.

[0016] 2. In this utility model, the elastic clamp inside the positioning cylinder can firmly clamp the suction tube and neuroendoscopy through the elastic action of the spring sheet, ensuring that these important surgical instruments will not loosen or fall off during the operation, providing reliable support for clear surgical vision and continuous operation.

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] Reference Figure 1 - Figure 3This utility model provides an embodiment of a multi-channel integrated stoma dynamic support device, including an arc-shaped block 1. The arc-shaped block 1 has an overall arc shape and is made of polyetheretherketone (PEEK), which has good biocompatibility and will not cause an immune response in the human body. It has high strength, providing stable support for brain tissue and resisting external forces during surgery. It has good chemical resistance and is not easily affected by chemicals in the brain. It has good X-ray permeability, which does not interfere with intraoperative imaging examinations such as CT and MRI, facilitating real-time observation of the surgical area by doctors. It can also be precisely shaped by heating to meet various needs. According to the patient's brain anatomy and surgical needs, two sets of positioning cylinders 2 are fixedly connected to the inner arc surface of the arc block 1. The positioning cylinder 2 is a through cylindrical tube. An elastic clamp 3 is provided on the inner side wall of the positioning cylinder 2. The elastic clamp 3 includes a slot 31. A spring piece 32 is provided on the inner side wall of the slot 31. The spring piece 32 is existing technology. One end of the two sets of positioning cylinders 2 can be connected to the suction tube and the other end can be connected to the endoscope. Through the elastic action of the spring piece 32, the tube inserted into it can be pressed. There are four sets of slots 31. All four sets of slots 31 are opened on the inner arc surface of the positioning cylinder 2.

[0024] Working principle: Before the intracerebral hematoma evacuation surgery, the arc-shaped block 1 is heated and shaped according to the specific condition of the patient's brain, so that its shape is adapted to the patient's cortical stoma and surrounding brain tissue. During the operation, the shaped arc-shaped block 1 is placed at the cortical stoma. Utilizing its arc structure and high strength characteristics, it separates and supports the cortical stoma, providing a stable space for subsequent surgical operations.

[0025] During the surgical preparation phase, the suction tube is inserted into one of the positioning tubes 2. When the suction tube is inserted, the spring clip 32 in the slot 31 uses its own elasticity to clamp and fix the suction tube, ensuring that the suction tube will not loosen or fall off during the operation. At the same time, the neuroendoscope is inserted into another positioning tube 2, and the neuroendoscope is also pressed and fixed by the spring clip 32. During the operation, the neuroendoscope is used for illumination and observation to clearly show the location and condition of the intracranial hematoma. The suction tube is used to aspirate blood clots, blood and other substances that need to be removed from the brain, keeping the surgical field clear and the surgical area clean.

[0026] If the surgeon finds that there is a lot of material to be removed from the brain tissue and the current device's opening range is insufficient, the surgeon will instruct the attending physician's assistant or nurse to push the entire device to increase its opening range, so as to better expose the surgical area and perform hematoma removal. Conversely, if it is found that the device has been open for too long and there is concern that it may cause damage to the brain tissue, the surgeon will ask the nurse to swing the device back a little to reduce the opening range and reduce pressure on the brain tissue. Throughout the adjustment process, the arc-shaped block 1 always maintains support for the cortical stoma, and the positioning tube 2 and elastic clamp 3 also continuously fix the suction tube and neuroendoscopy to ensure the smooth progress of the surgery.

[0027] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
