Description

Technical Field

[0001] This application relates to the field of medical assistive device technology, and in particular to a novel laryngeal foreign body forceps. Background Technology

[0002] A laryngeal foreign body forceps is a medical instrument used to remove foreign objects from the larynx, glottis, or upper respiratory tract. Due to the complex anatomy of the larynx, foreign objects can easily become lodged in narrow or concealed locations. Traditional forceps or ordinary forceps are often insufficient to safely and effectively remove these objects. Therefore, a laryngeal foreign body forceps was developed to address this need. The application of laryngeal foreign body forceps involves removing foreign objects while protecting vital structures such as the laryngeal mucosa and vocal cords. Laryngeal foreign body forceps are primarily used to remove food-related foreign objects, non-food-related foreign objects, and medical-related foreign objects from the vicinity of the larynx. Food-related foreign objects include fish bones, bone fragments, fruit pits, and nuts. Non-food-related foreign objects include toy parts swallowed by children, coins, and button batteries. Medical-related foreign objects include remnants of dentures, dental materials, and endotracheal tube fragments.

[0003] In clinical treatment, it is often found that long, sharp foreign objects such as fish bones and thin bones are stuck at both ends in the throat mucosa. If they are forcibly pulled out, it will directly cause mucosal tearing and bleeding. In addition, fish bones / bone fragments are brittle and are prone to breakage when subjected to uneven force. The remaining sharp points may move to a deeper part, affecting the treatment effect. Therefore, medical staff often use special scissors to operate.

[0004] Existing laryngeal foreign body forceps only have a single function, such as pure clamping or pure cutting. In the above situations, multiple instruments are required, which prolongs the operation time, increases the intensity of the operation for medical staff, and affects the patient's treatment experience. At the same time, each additional instrument increases the cost of sterilization and the time required for sterilization. Utility Model Content

[0026] Please see Figure 1 , Figure 2 , Figure 3 and Figure 4In one or more embodiments, a novel laryngeal foreign body forceps is provided, comprising a hollow outer shell 100, a connecting strap 101 disposed inside the hollow outer shell 100, a forceps head 119 disposed on one side of the hollow outer shell 100, and a handle disposed at the bottom of the other side of the hollow outer shell 100. The handle controls the opening and closing action of the forceps head 119 via the connecting strap 101. The forceps head 119 includes a first forceps body 102, a second forceps body 103, and a connecting seat 104. The connecting seat 104 has symmetrically formed fixing grooves 105 inside, and a movable rod 106 is movably connected inside the fixing groove 105. The other end of one movable rod 106 extends to the outside of the connecting seat 104 and connects to the surface of the first forceps body 102. The other end of one movable rod 106... One end extends to the outside of the connecting seat 104 and connects to the surface of the second clamp body 103. The surface of the movable rod 106 is fitted with a torsion spring 107. One end of the torsion spring 107 is connected to the inner wall of the fixing groove 105. The other end of one torsion spring 107 is connected to the surface of the first clamp body 102, and the other end of one torsion spring 107 is connected to the surface of the second clamp body 103. The surfaces of the first clamp body 102 and the second clamp body 103 are provided with clamping areas 109 and cutting edge areas 108 that are matched in position. The first clamp body 102 and the second clamp body 103 are arc-shaped and face away from the cutting edge area 108. When the clamp head 119 is open, one side of the first clamp body 102 and the second clamp body 103 abuts against one side of the hollow shell 100.

[0027] In this embodiment, the handle pulls the connecting seat 104 via the connecting strap 101, causing the first clamp body 102 and the second clamp body 103 to move into the hollow outer shell 100. Limited by the inner diameter of the hollow outer shell 100, the first clamp body 102 and the second clamp body 103 deflect around the movable rod 106, thereby achieving the closing operation of the clamp head 119. At this time, the torsion spring 107 is in a torsional state. When the handle stops pulling the connecting strap 101, the rebound force of the torsion spring 107 causes the first clamp body 102 and the second clamp body 103 to deflect in the opposite direction around the movable rod 106. The first clamp 102 and the second clamp 103 will drive the connecting seat 104 to move outward from the hollow shell 100. When using it, medical staff can use the cutting edge area 108 and the clamping area 109 to perform cutting and clamping actions. According to the actual treatment needs of the patient, medical staff can adjust the depth of the clamps and selectively use the clamping or cutting function, thereby reducing the number of medical instruments in the medical operation process, shortening the operation time, and effectively reducing the disinfection cost and disinfection time. It should be noted that the shape of the hollow shell 100 can be changed as needed, that is, modified into a bent shape, which is within the protection scope of this patent.

[0028] Please see Figure 1 , Figure 2 and Figure 5In some embodiments, the handle includes a fixed handle 110 and a movable handle 111. The fixed handle 110 is disposed on the surface of the hollow housing 100 and located on the side away from the pliers head 119. The movable handle 111 is provided with a movable pin 112, the other end of which is movably connected to the front of the hollow housing 100. A through hole 113 is provided inside the hollow housing 100. The top of the movable handle 111 extends through the through hole 113 into the interior of the hollow housing 100. One end of the connecting strap 101 is connected to one side of the connecting seat 104, and the other end of the connecting strap 101 is connected to the surface of the movable handle 111. A slot 114 is provided on the front of the fixed handle 110, and a rubber pad 115 is provided on the back of the movable handle 111. The surface of the rubber pad 115 can abut against the inner wall of the slot 114. Both the fixed handle 110 and the movable handle 111 are provided with finger insertion holes 118 inside.

[0029] In this embodiment, one finger passes through the finger insertion hole 118 of the fixed handle 110, and the thumb passes through the finger insertion hole 118 of the movable handle 111. The thumb exerts force to cause the bottom of the movable handle 111 to move towards the fixed handle 110 with the movable pin 112 as the center. At the same time, the movable handle 111, located above the movable pin 112 and inside the hollow outer shell 100, pulls the connecting strap 101 to cause the pliers head 119 to move into the hollow outer shell 100, thereby controlling the pliers head 119 to achieve a closing action; wherein the rubber pad 115 on the movable handle 111 The rubber pad 115 abuts against the surface of the fixed handle 110 until it abuts against the inner wall of the slot 114. The rebound effect of the rubber pad 115 helps to improve the stability of the contact between the movable handle 111 and the fixed handle 110, thereby reducing the probability of foreign objects falling out due to loosening of the handle when clamping foreign objects. The stability between the movable handle 111 and the fixed handle 110 is affected by the rebound effect of the rubber pad 115. When the forceps head 119 needs to be opened, medical staff can use their thumbs to assist in applying force to ensure that the opening action of the forceps head 119 is carried out smoothly.

[0030] Please see Figure 1 , Figure 3 and Figure 4 In some embodiments, a camera 116 is provided on one side of the connector 104, and a power cord 117 is provided inside the connector 101. One end of the power cord 117 passes through the connector 104 and is electrically connected to the camera 116. Both the first clamp body 102 and the second clamp body 103 have clearance grooves inside. The clearance grooves are used to prevent the clamp head 119 from abutting against the camera 116 when it is closed.

[0031] In this embodiment, the camera 116 is a miniature structure and can transmit the images collected inside the throat to the outside via wired or wireless means to assist the doctor's operation. Moreover, when configuring the camera 116, in order to provide accurate position reference, the camera 116 is set at the center of the connector 104. The purpose is to facilitate the determination of the position of the foreign object in the throat relative to the clamping area 109 and the cutting edge area 108 when the forceps head 119 is in the throat, so as to adjust the depth of the forceps head 119. The opening of the clearance groove ensures that the forceps head 119 will not come into contact with the camera 116 when it is closed, so as to ensure that the operation of the camera 116 is not affected. The power cord 117 is provided to supply power to the camera 116.

[0032] It should be noted that the specific model and specifications of the camera 116 and power cord 117 in this application need to be selected and determined according to the actual specifications of the device. The specific selection calculation method adopts the existing technology in the field, so it will not be described in detail here. Its power supply and its principle are clear to those skilled in the art, so they will not be described in detail here. The connection and installation of its various parts and the signal transmission principle are well known technologies in the field.

[0033] Please see Figure 1 , Figure 2 and Figure 4 In some embodiments, the clamping section 109 has a continuous groove, and the cutting edge section 108 is located on the side of the clamping section 109 near the connecting seat 104.

[0034] In this embodiment, the clamping section 109 of the continuous groove increases the friction when the clamping section 109 comes into contact with the foreign object, thereby improving the stability of the clamping section 109 when clamping the foreign object.

[0035] Specifically, the working principle of the novel laryngeal foreign body forceps provided in this application is as follows: One finger passes through the finger insertion hole 118 of the fixed handle 110, and the thumb passes through the finger insertion hole 118 of the movable handle 111. The hollow outer shell 100 at one end of the forceps head 119 is inserted into the patient's throat. The camera 116 is used to know the specific situation inside the throat, so as to determine the position of the foreign object in the throat relative to the clamping area 109 and the cutting edge area 108, so as to adjust the depth of the forceps head 119. Then, confirm that the clamping area 109 or the cutting edge area 108 is in a suitable position. Then, use your thumb to force the bottom of the movable handle 111 to move towards the fixed handle 110 with the movable pin 112 as the center. At the same time, the movable handle 111 above the movable pin 112 and located inside the hollow shell 100 will pull the connecting strap 101 to move the pliers head 119 into the hollow shell 100. Due to the inner diameter of the hollow shell 100, the first pliers body 102 and the second pliers body 103 deflect around the movable rod 106, thereby realizing the closing operation of the pliers head 119, and thus realizing the clamping or cutting action on foreign objects.

[0036] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this application, and are not intended to limit them. Although this application has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features therein. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of this application.
