Description

Technical Field

[0001] The utility model relates to the field of surgical supplies, in particular to a medical consumable for protecting mucous membranes in otolaryngology surgeries. Background Art

[0002] With the continuous improvement of medical technology, minimally invasive surgery has been increasingly applied in clinical practice and has achieved very good results. Minimally invasive surgery has the advantages of less trauma, less pain, and faster recovery. It also reduces the harm of traditional surgery to the human body and greatly reduces the inconvenience and pain caused to patients during disease treatment. Therefore, patients have a high degree of acceptance and a good satisfaction rate. Among minimally invasive surgeries, endoscopic surgery is a more commonly used method in neurosurgery. It utilizes the natural gaps in the human body's natural cavities such as the nasal cavity, sinuses, and nasopharynx to fully expose and maximally remove the diseased tissue at the base of the skull. Due to its advantages such as short path, wide field of view, clear imaging, less trauma, fast postoperative recovery, and low cost, it has been gradually promoted in neurosurgery and has achieved good social and economic benefits. However, there are some problems with transnasal surgery. Transnasal surgery is equivalent to using the nasal cavity as a channel for surgical instruments to enter and exit. Because the nasal cavity is narrow and contains physiological and anatomical structures such as nasal concha and nasal septum, it is very easy for the instruments to repeatedly enter and exit the nasal cavity, causing collision and damage to the nasal lining mucosa. In addition, the nasal lining mucosal tissue is very fragile and delicate, with rich blood supply. Accidental collision will inevitably cause mucosal damage and bleeding, which is not only unnecessary harm to the patient, but also bleeding of the nasal lining mucosa will cause repeated contamination of the neuroendoscope lens, resulting in unclear vision, interference with the surgical process, and increased surgical risks.

[0003] Therefore, various protective devices have been developed for nasal surgery. These protective devices are generally cylindrical structures, such as a cylindrical structure made of a protective film. Since the surrounding side of this protective device is a closed surface, after it is attached to the inner wall of the nasal cavity, the skin lacks air permeability, which makes the surgical patient feel uncomfortable. Although there are also cylindrical structures made of woven meshes, this product can provide better air permeability for the skin. However, the mesh size of this woven mesh is not fixed, and the mesh is easily enlarged by surgical instruments, causing collision and damage to the inner wall mucosa of the nasal cavity, and it cannot play an effective protective role. Therefore, it is necessary to improve the current protective devices. Utility Model Content

[0004] In view of this, the present invention aims to address the deficiencies in the prior art, and its main purpose is to provide a mucosal protection medical consumable for ENT surgery, which can effectively solve the problem that the existing protection devices have poor air permeability to the skin or cannot provide effective protection.

[0005] In order to achieve the above purpose, the utility model adopts the following technical solutions:

[0006] A mucosal protection medical consumable for ENT surgery includes a main body, which is a mesh structure woven by silk threads. The main body has a surgical channel and a plurality of mesh holes connecting the outside of the main body and the surgical channel, and the cross-overlapping joints of the silk threads are fused and fixed together. In addition, the main body includes an inner protective part for extending into the ENT cavity, a transition part, and an outer protective part located outside the ENT cavity. The inner protective part, the transition part, and the outer protective part are integrally formed and connected in sequence from front to back to form the aforementioned surgical channel.

[0007] As a preferred solution, the silk thread is a monofilament structure, which makes weaving simple.

[0008] As a preferred solution, the thread is a thermoplastic elastomer having the supporting characteristics of free stretching and expansion.

[0009] As a preferred solution, the inner protective part is a tubular structure that matches the ENT surgery cavity, so as to better insert into and adapt to the inside of the ENT cavity.

[0010] As a preferred solution, the transition portion includes a front section and a rear section connected in sequence, the front section is a trumpet-shaped structure opening forward, and the rear section is a trumpet-shaped structure opening backward, so as to better adapt to the opening of the ear, nose and throat cavity.

[0011] As a preferred solution, the outer protective part is a truncated cone structure with an outer diameter gradually increasing from front to back, so as to better protect the outer surrounding of the ear, nose and throat cavity.

[0012] Compared with the prior art, the utility model has obvious advantages and beneficial effects. Specifically, it can be seen from the above technical solution that:

[0013] This product is woven with silk threads to form a surgical channel and multiple mesh holes. The mesh holes provide good air permeability to the skin, making it more comfortable for surgical patients to use. The silk threads are fused and fixed together at the cross-joints, so that the size of the mesh holes is fixed and cannot be enlarged by surgical instruments, thereby preventing surgical instruments from colliding with and damaging the mucous membrane of the inner wall of the ear, nose and throat cavity. It effectively plays a protective role, brings convenience to surgical operations, is conducive to reflecting the minimally invasive characteristics of endoscopic surgery, and accelerates the recovery of the ear, nose and throat cavity function after surgery.

[0025] Please refer to Figures 1 to 4 As shown, it shows the specific structure of a preferred embodiment of the utility model, including a main body 10.

[0026] The body 10 is a mesh structure woven by surrounding silk threads 101, and the body 10 has a surgical channel 102 and a plurality of mesh holes 103 connecting the outer side of the body 10 and the surgical channel 102, and the cross-overlapping joints of the silk threads 101 and the silk threads 101 are fused and fixed together, so that the interwoven silk threads 101 cannot be displaced from each other, and the size of the mesh holes 102 is fixed and cannot be enlarged or reduced. In the present embodiment, the silk threads 101 are monofilament structures, which makes weaving simple, and the silk threads 101 are thermoplastic elastomers, such as TPU, etc., which have the supporting characteristics of free expansion and contraction, and the cross-overlapping joints of the silk threads 101 and the silk threads 101 are fused and fixed together by hot melting, which is easy to manufacture.

[0027] The main body 10 includes an inner protective portion 11 for extending into the ENT cavity, a transition portion 12, and an outer protective portion 13 located outside the ENT cavity.
