Description

Technical Field

[0001] The utility model belongs to the technical field of mandibular osteomyelitis surgery equipment and relates to a surgery auxiliary positioning lighting device, in particular to a mandibular osteomyelitis surgery auxiliary positioning lighting device. Background Art

[0002] In the surgery for mandibular osteomyelitis, since the lesion is located on the jaw, when the surgery is performed from the mouth, the location and boundary of the lesion can be located, so that the doctor can more accurately remove the diseased tissue. During the operation, the patient needs to keep his mouth open, but because the oral cavity is small and deep, the vision is poor, and lighting equipment is needed. The existing oral lighting lamps for dental surgery are installed by sliding the connecting rod. The connecting rod is long, and it is not convenient to rotate and adjust the irradiation angle of the oral lighting lamp. It is impossible to accurately aim at the surgical site, and subtle lesions are often not seen clearly. The burden on the surgeon's eyes is greatly increased. At the same time, the oral lighting lamp directly irradiates the patient, which is easy to cause eye discomfort to the patient, making the patient feel glare and other discomfort.

[0003] After searching, it is found that a Chinese patent document discloses an oral lighting lamp for dental surgery [Application No.: 202121611283.5; Announcement No.: CN215174467U]. This oral lighting lamp for dental surgery can adjust the damping of the anti-slip sleeve and the fixing seat by turning the nut, so that the operator can turn and adjust the angle of the lampshade to view the internal situation of the patient's mouth. The installation design of the universal tube can facilitate the operator to flexibly adjust the angle of the lampshade and quickly fix the position of the lampshade; by fixing the welding handles at the upper and lower ends of the lampshade, the operator can pull the lampshade conveniently, which is easy to use. The design of the shading block can turn the direct light of the light shining on the shading block into scattered light, preventing the light from directly shining on the patient and causing discomfort to the patient's eyes.

[0004] Although the oral lighting device for dental surgery disclosed in this patent can fine-tune the light, it is difficult for the lighting device to match the depth of mandibular osteomyelitis surgery, and needs to be adjusted in real time as the patient's head is moved during the positioning process, which prolongs the operation time. In addition, the location and boundaries of the mandibular osteomyelitis lesions require preoperative CT scan confirmation, which is difficult to distinguish with the naked eye during the operation, resulting in the doctor often having to spend a lot of time judging the boundaries of the lesions during the operation. Utility Model Content

[0005] The purpose of the utility model is to address the above-mentioned problems in the existing technology and propose an auxiliary positioning lighting device for mandibular osteomyelitis surgery. The technical problem to be solved by the utility model is: how to achieve real-time positioning of the position and boundary of the mandibular osteomyelitis lesion and maintain the lighting of the surgical field without having to continue adjusting the lighting after adjusting the patient's head position, thereby improving the efficiency of the surgery.

[0006] The purpose of the utility model can be achieved through the following technical solutions:

[0007] A surgical auxiliary positioning lighting device for mandibular osteomyelitis comprises a positioning guide plate, the positioning guide plate comprises a dental brace and a wound covering plate, a connecting plate is integrally formed between the dental brace and the wound covering plate, a sliding groove is provided at the rear end of the connecting plate, a sliding block is slidably connected in the sliding groove, a bolt is fixed at the upper position of the rear end of the sliding block, a nut is threadedly connected on the bolt, a long groove for the bolt to slide is provided on the connecting plate, the sliding block is made of rubber, a connecting mechanism is provided at the lower position of the rear end of the sliding block, a supporting mechanism is provided on the connecting mechanism, a second connecting tube is provided on the supporting mechanism, a second gooseneck is fixed on the second connecting tube, a lampshade is fixed at the end of the second gooseneck away from the second connecting tube, a lamp bead is fixed in the lampshade.

[0008] The working principle of the utility model is as follows: through preoperative spiral CT examination, the location and boundary of the mandibular osteomyelitis lesion are clarified, and then a positioning guide plate adapted to the tooth shape corresponding to the patient's osteomyelitis lesion is made through 3D printing according to the CT examination data. When installed and used, the wound surface covering plate is covered on the wound surface, and the braces are put on the teeth corresponding to the wound surface to realize the installation of the positioning guide plate, and the slider is slid in the slide groove to adapt its height in the connecting plate so that the supporting mechanism can be installed in the oral cavity. After determining the appropriate height, the nut is tightened on the bolt by rotation to fix the position of the slider on the connecting plate, and then the supporting mechanism is adjusted to keep the patient's mouth open for surgery. In this process, the connecting mechanism is connected through the connecting mechanism. The position of the supporting mechanism is adapted by twisting the first gooseneck tube. The first gooseneck tube in the connecting mechanism is also a prior art and will not be described in detail below. A rubber layer is provided in the second connecting tube for interference fit with the internal threaded rod, and the lighting height can be adjusted through the interference fit position when the second connecting tube is installed. During the operation, the lampshade can be held by hand to align the lamp beads with the direction of the wound covering plate. During the process of holding the lampshade and applying force, the second gooseneck tube changes the position of the lampshade and the lamp beads by twisting. The lamp beads are electrically connected to an external power supply, so that the mandibular osteomyelitis wound, lighting and patient's head are all in a relatively static state. There is no need to adjust the lighting when the patient's head moves, and the wound covering plate plays a positioning role so that the doctor can clearly know the position of the wound.

[0009] The connecting mechanism comprises a connecting block and a first connecting cylinder, and a first gooseneck tube is fixedly connected between the connecting block and the first connecting cylinder.

[0010] With the above structure, the connecting block follows the slider to slide in the long groove, the first connecting tube slides on the supporting mechanism, the first gooseneck tube twists to adapt to the position between the slider and the first connecting tube, and a universal connection is achieved through the characteristics of the first gooseneck tube itself.

[0011] The top end of the long slot is connected with a notch arranged on the connecting plate, and both the connecting block and the bolt can slide in the notch.

[0012] By adopting the above structure, before installing and using the positioning guide plate, the bolts and the connecting block can be passed through the notch on the connecting plate, so that the slider follows the bolts and the connecting block into the slide groove (the slider is made of rubber so that it can move in the curved slide groove), and after use, the slider is removed in the above manner to separate the connecting mechanism and the positioning guide plate, so that the universal connecting mechanism and the supporting mechanism can adapt to the disposable positioning guide plates customized for different patients, thereby saving the cost of surgical tools for mandibular osteomyelitis.

[0013] The supporting mechanism includes an internal threaded rod rotatably connected to the inner wall of the first connecting tube, the inner wall of the internal threaded rod is threadedly connected to the threaded rod, a rotating member is fixed to the top of the threaded rod, a rotating shaft is fixed to the top of the rotating member, a first resistance plate is rotatably connected to the top of the rotating shaft, and a second resistance plate is fixedly connected to the bottom end of the internal threaded rod.

[0014] By adopting the above structure, the first contact plate and the second contact plate wrapped with nitrile rubber are clamped between the upper jaw and the lower jaw in the patient's mouth according to the position of the patient's mandibular osteomyelitis (the position where the support mechanism is installed is far away from the surgical operation range in the oral cavity), and the internal threaded rod is rotated to make it rotate in the first connecting tube to adjust the support angle of the second contact plate on the lower jaw, and the rotating part is rotated (the rotating part is a block with a regular hexagonal cross-section, which is convenient for applying force). The threaded rod rotates with the rotating part, and the threaded rod and the threaded hole in the internal threaded rod generate threaded transmission to extend or shorten the distance between the first contact plate and the second contact plate, so that the degree of opening of the patient's mouth during surgery can be adjusted.

[0015] A rubber layer is fixedly connected to the inner wall of the second connecting tube, and the second connecting tube is interference-fitted with the internal threaded rod through the rubber layer.

[0016] By adopting the above structure, applying force to the second connecting tube can adjust the position of the second connecting tube on the internal threaded rod, and the rubber layer can achieve interference fit so that the adjusted position does not slide. Continuously rotating the rotating part can separate the threaded rod from the internal threaded rod, so that the second connecting tube can be removed from the internal threaded rod, which is convenient for replacing parts.

[0017] The rotating shaft is rotatably connected to the first contact plate via a bearing.

[0018] By adopting the above structure, when the first resistance plate resists the upper jaw, when the rotating part rotates, the rotating shaft drives the movable end of the bearing to rotate, thereby ensuring that the first resistance plate will not rotate with the rotating part during the process of adjusting the overall height of the supporting mechanism, avoiding the first resistance plate from rotating in the oral cavity and producing large movements, realizing the relative static relationship between the first resistance plate and the oral cavity, and achieving stability during the process of adjusting the degree of oral opening.

[0019] The materials of the braces, connecting plates and wound covering plates are all PA2200 nylon.

[0020] Using the above structure, PA2200 nylon is used as the overall 3D printing material of the positioning guide, which can provide good support and stability.

[0021] Compared with the prior art, the auxiliary positioning lighting device for mandibular osteomyelitis surgery has the following advantages:

[0022] 1. By setting a positioning guide to cover and position the mandibular osteomyelitis lesion, the doctor can grasp the position and boundary of the mandibular osteomyelitis lesion in real time, so that it can be accurately removed, improve the efficiency of the operation and reduce the trauma to the patient. At the same time, through the arbitrarily deformable characteristics of the second gooseneck tube and the interference fit installation method of the second connecting tube, the lamp beads can be closely aligned with the wound surface when adjusting the height, and remain connected to the positioning guide plate, so that the lighting area and the wound covering plate are in a relatively static relationship, so that when the doctor adjusts the patient's head, the lighting follows the movement without additional adjustment, which greatly improves the efficiency of the operation.

[0023] 2. The supporting mechanism and the positioning guide plate are connected by setting a connecting mechanism, and the first gooseneck tube is flexibly adjusted to adapt to the surgical positions in the oral cavity of different patients. The positioning guide plate and the supporting mechanism at different positions in the oral cavity are connected without blocking. The distance between the first contact plate and the second contact plate in the supporting mechanism can be adjusted through threaded transmission to adjust the degree of opening of the patient's mouth. The supporting mechanism is flexible and can be detachably connected to the connecting plate through a slider, so that the connecting mechanism and the connecting supporting mechanism can adapt to multiple surgeries and save surgical costs.

[0040] The working principle of the utility model is as follows: through preoperative CT examination, the location and boundary of the mandibular osteomyelitis lesion are clarified, and then a positioning guide plate adapted to the tooth shape corresponding to the patient's osteomyelitis lesion is made through 3D printing according to the CT examination data. Before installing and using the positioning guide plate, the bolt 3 and the connecting block 5 can be passed through the notch 103 on the connecting plate 1, so that the slider 2 follows the bolt 3 and the connecting block 5 into the slide groove 101 (the slider 2 is made of rubber, so that it can move in the curved slide groove 101), and after use, the slider 2 is removed in the above manner to separate the connecting mechanism from the positioning guide plate.

In the process that the first contact plate 11 contacts the upper jaw, when the rotating member 12 rotates, the rotating shaft 14 drives the movable end of the bearing 13 to rotate, so as to ensure that the first contact plate 11 will not rotate with the rotating member 12 during the process of adjusting the overall height of the supporting mechanism, so as to avoid the first contact plate 11 from rotating in the oral cavity to produce a large movement, so as to achieve a relative static relationship between the first contact plate 11 and the oral cavity, and a rubber The rubber layer 20 is used for interference fit with the internal threaded rod 9, and when the second connecting tube 16 is installed, the lighting height can be adjusted through the interference fit position. Applying force to the second connecting tube 16 can adjust the position of the second connecting tube 16 on the internal threaded rod 9. The rubber layer 20 can achieve interference fit so that the adjusted position does not slide. During the operation, the lampshade 18 can be held by hand to align the lamp beads 19 with the wound covering plate 8.
