Description

An endoscope suitable for intraorbital surgery

technical field

The invention relates to the field of medical instruments, in particular to an endoscope suitable for orbital surgery.

Background technique

Visualization in orbital surgery has been a major challenge for craniomaxillofacial surgeons and ophthalmologists. The human orbit is a quadrangular pyramid-shaped cavity, which contains extraocular muscles for coordinated movement, cushion-like adipose tissue, nutrition, and blood vessels and nerves that innervate important tissues. The structure is complex and delicate. The bony framework and eye contents not only maintain a normal appearance, but also have eye movement and visual functions. Orbital surgery, especially retro-ocular surgery, requires extremely high surgical field of view clarity due to the special spatial structure. It is necessary to avoid damage to these important orbital contents, and to have a certain space to allow the input of surgical instruments, which makes the current surgery difficult. Large, high-risk, time-consuming, and even some operations cannot be carried out. Therefore, surgeons are very eager to have a precise, minimally invasive, and effective instrument to assist in the visualization of orbital surgery.

At present, the traditional CT, MRI, and ultrasound imaging examinations have important guiding significance in the diagnosis of orbital diseases. They can provide important information such as the volume, distribution, and general shape of soft tissues. However, CT and MRI need to scan the tissue in layers according to thickness, and then synthesize the required images through software. A lot of information is lost in the process of collection and transformation, and it is impossible to truly restore the fine structure of the orbit, which makes it difficult for these instruments to be used in surgery provide convenience.

The surgical navigation system simulates the operation through preoperative 3D or model, and uses real-time CT or MRI3D technology to restore the structure and position of the surgical area during the operation. Although this technique can accurately locate the surgical site, it is difficult to distinguish the surrounding soft tissue in such a complex area of orbital soft tissue, which limits its application in fine orbital surgery.

Fenestration of the optic nerve sheath, pathological biopsy or resection of orbital tumors, removal of foreign bodies, and many other operations that may involve the retrobulbar area can only be achieved through orbital bone fenestration or separation of the eyeball or other soft tissues. Limited by the defects of visualization technology, no effective minimally invasive technology has been developed to solve such problems.

Endoscopy is a minimally invasive technique that provides better visibility and light during orbital surgery, especially in the retrobulbar region; allows for magnification of images; and allows for additional surgical aids such as surgical navigation in reconstruction The application in surgery provides convenience. However, it is difficult to distinguish between adipose tissue and optic nerve in the image transmitted by the endoscope at present, making it difficult to avoid damage to the optic nerve. Moreover, the field of view of the endoscope is often blocked by soft tissue or blood in the orbit, making it difficult to ensure a normal surgical field of view. Although the prospect of endoscopy in orbital surgery is promising, it is limited in actual operation and has not been widely developed.

Example 1

Please refer to Fig. 1-2, an endoscope suitable for intraorbital surgery, including a handle 1, one end of the handle 1 is fixedly connected to the working mirror tube, the working mirror tube includes a fixing part 2, and one end of the fixing part 2 is connected to the handle 1 is fixedly connected, the other end of the fixed part 2 is fixedly connected to the curved part 3, the end of the curved part 3 is connected to the front end of the camera 4, and the end of the handle 1 away from the fixed part 2 is fixedly connected to the control seat 5, and the control seat 5 is provided with The control handle 9 is provided with an injection seat 7 at the top of the fixed part 2, and an injection port 8 is opened on the injection seat 7.

The end portion of the control seat 5 is fixedly connected to the video line 6, and the front end of the camera 4 is provided with a working channel 10, a lens 11 and a lighting lamp sheet 12, and the working mirror tube is provided with two optical fiber bundles, two optical fiber bundles, and two optical fiber bundles. The fiber bundles are light beams and image bundles respectively. The ends of the light beams are connected to the light sheet 12, and the ends of the image bundles are connected to the lens 11. The working mirror tube is provided with scales.

Example 2

Please refer to Fig. 1-2, other content of this embodiment is the same as embodiment 1, and difference is: the length of described bending part 3 is 6cm, and the diameter of described working mirror tube is 4mm, and the diameter of described working channel 10 The diameter is 2mm.

This endoscope has the following features:

1. Optical fiber endoscope: The working mirror tube of the endoscope is a beam fiber body, and there are two optical fiber bundles inside: one is a beam, which is used to transmit the light generated by the cold light source to the surface of the object being observed. The surface of the object to be observed is illuminated; the other is the image beam, which arranges tens of thousands of optical fibers with a diameter of less than 1 micron into a bundle in a row, one end is aligned with the eyepiece, and the other end is aligned with the object to be observed through the objective lens On the surface of the object, the doctor adjusts the appropriate surgical position through the scale of the working mirror tube, and can see the situation in the orbit very intuitively through the eyepiece at the front end of the camera 4, which is convenient for timely and accurate diagnosis of the disease. The front end of the camera can be curved in the orbit through the control handle and handle to avoid damage to the optic nerve and blood vessels in the eye. More importantly, it can adapt to the requirement of constantly adjusting the angle of the working mirror in the narrow tapered structure of the orbit.

2. Length design: The length of the flexible working mirror is 6cm, which is different from the working length of other endoscopes. The diameter of the human eyeball is 24mm, and the safe operating distance from the front edge of the orbital wall to the back of the eyeball is 4cm. The length of the curved part is designed to be 6cm, and the curved part is made of soft materials to meet the needs of the operation. It not only saves manufacturing cost, but also improves the flexibility of operation.

3. Diameter design: Orbital surgery requires fine instruments, and the smaller the diameter of the working mirror tube of the endoscope, the less damage to the orbital tissue. The design diameter of the working tube diameter in this solution is 4 mm, which is much finer than the existing instruments for entering the orbit, and the trauma is minimized.

4. Single hole design: a working mirror tube with a diameter of 4mm, including a working channel 10 with a diameter of 2mm. The working channel 10 is used to input materials that need to be injected into the retro-orbit (including autologous fat, silica gel, hyaluronic acid, etc.)

The overall design of the working mirror is small, and disposable simple materials can be used to design a disposable working soft mirror. At present, hospital operating rooms require strict disinfection of instruments, and working mirrors need to be disinfected repeatedly. Disposable working soft mirror not only avoids repeated use in surgery, light mirror shifting, and reduced clarity; at the same time, it avoids damage to the working mirror due to repeated disinfection. Therefore, the disposable working soft mirror improves the accuracy of the operation, simplifies the operation process of the operating room, and saves manpower and material resources.

Finally, it should be noted that: the above is only a preferred embodiment of the present invention, and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the foregoing embodiments, for those skilled in the art, it still The technical solutions recorded in the foregoing embodiments may be modified, or some technical features thereof may be equivalently replaced. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention shall be included within the protection scope of the present invention.
