Description

Technical Field

[0001] The present application belongs to the technical field of surgical instruments, and more specifically, to a transoral surgical endoscopic system. Background Art

[0002] As people pay more attention to health and medical detection technology advances, the early detection rate of head and neck diseases such as laryngeal tumors and submandibular gland diseases has increased year by year. Transoral surgery has become one of the preferred options for the treatment of such diseases due to its advantages of reaching the lesion area directly through the natural channels of the oral cavity without the need for external incisions. This has led to an increasing demand for transoral surgical endoscopes, which play a key role as the doctor's "eyes" during surgery, allowing doctors to intuitively observe lesions in hidden areas such as the deep oral cavity, throat, and even hypopharynx.

[0003] Limited field of view is one of the core problems faced by endoscopes in transoral surgery. Due to the limitations of the oral anatomy, it is difficult for endoscopes to obtain a wide and comprehensive field of view. During transoral surgery, traditional endoscopes can only focus on local areas, and it is difficult to simultaneously observe surrounding potential diseased tissues or abnormal structures, which can easily lead to missing lesions and increase the risk of postoperative recurrence in patients. Moreover, when surgical instruments are operated in the oral cavity, the obstruction of the instruments will further reduce the effective field of view of the endoscope, and doctors often fall into the dilemma of "seeing the leopard in the tube", unable to accurately control the overall operation.

[0045] Please also read Figure 1-Figure 10 , the transoral surgical endoscope system provided in the embodiment of the present application is now described.

[0046] A transoral surgical endoscopic system, see Figure 1 , Figure 1 The schematic diagram of the use state of the transoral surgical endoscope system provided in the embodiment of the present application includes an endoscope support 100. Figure 2 , Figure 2 The present invention is a schematic structural diagram of an endoscope bracket 100 provided in an embodiment of the present application, wherein the endoscope bracket 100 includes an endoscope fixing bracket 110 for mounting an endoscope 400, a flexible cutting tube 120 is provided at the front end of the endoscope fixing bracket 110, a flexible hinge 130 is provided at the end of the flexible cutting tube 120 away from the end of the endoscope fixing bracket 110, the flexible cutting tube 120 and the flexible hinge 130 are provided with a cavity for the endoscope 400 to pass through, and an endoscope driving mechanism for controlling the bending and extension of the endoscope 400 is provided on the endoscope fixing bracket 110.

[0047] The present application uses a flexible cutting tube 120 to adapt to the shape of the oral cavity, making it easier for the endoscope 400 to extend into the oral cavity. The flexible hinge 130 is controlled to bend by an endoscope driving mechanism, so that the endoscope 400 can be controlled to bend, and surrounding potential diseased tissues can be observed to avoid omissions. The endoscope driving mechanism can also drive the endoscope to extend and retract along the length direction of the flexible hinge 130, so that the endoscope's field of view can penetrate deeper and narrower areas.

[0048] In some embodiments of the present application, see Figure 4 and Figure 5 The endoscope driving mechanism includes a bending assembly, which includes a first motor 111, a second motor 112, two first steel wires and two second steel wires. The first motor 111 and the second motor 112 are respectively connected to a first driving rod 113 and a second driving rod 114. The first ends of the two first steel wires and the two second steel wires pass through a flexible hinge 130, and the second ends of the two first steel wires and the two second steel wires pass through a flexible cutting tube 120 and are respectively wound around the first driving rod 113 and the second driving rod 114, and the two first steel wires are the same steel wire, and the two second steel wires are the same steel wire.

[0049] When the first motor 111 and the second motor 112 drive the first drive rod 113 and the second drive rod 114 to rotate clockwise at the same time, the first steel wire and the second steel wire drive the flexible hinge 130 to bend to the right, so that the endoscope bends to the right. When the first motor 111 and the second motor 112 drive the first drive rod 113 and the second drive rod 114 to rotate counterclockwise at the same time, the first steel wire and the second steel wire drive the flexible hinge 130 to bend to the left, thereby driving the endoscope to bend to the left at the same time. When the first motor 111 drives the first drive rod 113 to rotate counterclockwise, and the second motor 112 drives the second drive rod 114 to rotate clockwise, the first steel wire and the second steel wire drive the flexible hinge 130 to bend upward, thereby driving the endoscope to bend upward. When the first motor 111 drives the first driving rod 113 to rotate clockwise, and the second motor 112 drives the second driving rod 114 to rotate counterclockwise, the first steel wire and the second steel wire drive the flexible hinge 130 to bend downward, thereby driving the endoscope to bend downward, so as to realize the movement of the endoscope in four directions of up, down, left and right, observe the area around the lesion, avoid missing the lesion, and accurately control the overall operation. The above control logic is not limited, and the control logic of the motor can be determined according to the actual situation, which will not be described one by one here.

[0050] In other embodiments of the present application, other structures may also be used to drive the flexible hinge 130 to bend, and the present application does not limit this.

[0051] In some embodiments of the present application, see Figure 3-Figure 5 , Figure 3 Schematic diagram of the structure of the endoscope support provided in the embodiment of the present application Figure 2 , Figure 4 Schematic diagram of the internal structure of the endoscope fixing bracket provided in the embodiment of the present application Figure 1 , Figure 5 Schematic diagram of the internal structure of the endoscope fixing bracket provided in the embodiment of the present application Figure 2 .

[0052] The endoscope driving mechanism also includes a telescopic component, which includes a third motor 141. The third motor 141 is connected to a third driving rod 142. The third driving rod 142 is transmission-connected to a limiting component 140. The limiting component 140 is rotationally connected to the endoscope fixing bracket 110, and is used to drive the endoscope to reciprocate on the endoscope bracket 100.

[0053] The third motor 141 drives the third driving rod 142 to rotate, and the third driving rod 142 drives the limiting assembly 140 to rotate on the fixed bracket through the transmission mechanism. When the limiting assembly 140 rotates, it drives the endoscope to extend forward or retract backward on the endoscope bracket 100, so that the endoscope can be extended and retracted along the length direction of the flexible hinge 130, so that the field of view of the endoscope can penetrate deeper and narrower areas.

[0054] In some embodiments of the present application, see Figure 4-Figure 6 , Figure 6 The cross-sectional structure diagram of the limit assembly provided in the embodiment of the present application, the limit assembly 140 includes a limit shell 143 and a rotating shaft 145, the rotating shaft 145 is fixedly connected to the shell, the rotating shaft 145 is transmission-connected to the third driving rod 142, and a limit member 144 is arranged on the outer side of the limit shell 143, and the limit member 144 is detachably connected to the endoscope.

[0055] The third driving rod 142 can be driven by a gear, a belt, a steel wire or other structures to drive the rotating shaft 145 to rotate. The specific transmission structure is not limited in this application. The rotating shaft 145 can drive the limit housing 143 to rotate, thereby driving the limit member 144 disposed on the outside to move. The limit member 144 is connected to the endoscope, thereby driving the endoscope to move along its length direction and penetrate into a deeper and narrower area.

[0056] In some embodiments of the present application, see Figure 3-Figure 6 The outer sleeve of the rotating shaft 145 is provided with a damping spring 146, one end of the damping spring 146 abuts against the rotating shaft 145, and the other end abuts against the limiting housing 143, and is used to press the rotating shaft 145 against the endoscope fixing bracket 110. The friction force when the rotating shaft 145 rotates is increased to provide damping, so that the rotating shaft 145 remains relatively stable when rotating, so that the endoscope remains stable in the axial direction, and the endoscope is prevented from sliding during surgery.

[0057] In some embodiments of the present application, see Figure 6 One end of the limiting member 144 is hinged to the limiting shell 143 , and the other end is clamped to the endoscope, and there is damping between the limiting member 144 and the limiting shell 143 .

[0058] Specifically, the stopper 144 is provided with a groove, and the endoscope is provided with a corresponding protrusion. When in use, the protrusion is inserted into the groove to quickly connect the endoscope and the stopper 144. The groove and the protrusion can slide relative to each other. When the stopper 144 rotates, the circular motion of the stopper 144 is converted into the linear motion of the endoscope. There is damping between the stopper 144 and the stopper housing 143, but the endoscope is always kept in a compressed state.

[0059] In some other embodiments of the present application, a torsion spring may also be provided on the limiting member 144 so that the limiting member 144 can always press the endoscope tightly.

[0060] In some embodiments of the present application, see Figure 4 The endoscope fixing bracket 110 is clamped with an endoscope card 150, and the endoscope card 150 is used to clamp the endoscope on the endoscope fixing bracket 110. The endoscope card 150 can limit the endoscope to prevent the endoscope from coming off the endoscope fixing bracket 110.

[0061] In some embodiments of the present application, see Figure 2 and Figure 4 A trumpet-shaped endoscope guide tube 115 is disposed inside the endoscope fixing bracket 110 , and a smaller diameter end of the endoscope guide tube 115 is connected to the flexible cutting tube 120 with a smooth transition.

[0062] The endoscope guide tube 115 is configured to be trumpet-shaped, which can facilitate the endoscope to extend into the flexible cutting tube 120 and the flexible hinge 130 when installing the endoscope, thereby preventing the endoscope end from colliding and protecting the endoscope end.

[0063] In some embodiments of the present application, see Figure 2 The flexible cutting tube 120 includes a first tube section 121 and a second tube section 122. A wire combing partition 123 is provided between the first tube section 121 and the second tube section 122. The wire combing partition 123 is provided with four mutually separated through holes for the steel wires to pass through.

[0064] Since the flexible cutting tube 120 is a hose, when it is bent, the four steel wires passing through the inside thereof for controlling the flexible hinge 130 are easily tangled together. By setting a steel wire combing partition 123 and passing each steel wire through a through hole on the steel wire combing partition 123, the four steel wires can be combed to prevent the steel wires from being tangled together.

[0065] The endoscope tube 160 passes through the flexible cutting tube 120 and is connected to the flexible cutting tube 120 with a smooth transition, and is used to extend into a medical endoscope. The endoscope tube 160 is used in combination with a medical endoscope. The model of the medical endoscope can be selected according to actual conditions and is not limited here.

[0066] In other embodiments of the present application, the flexible cutting tube 120 can also be arranged into three sections, four sections, etc. according to actual needs, and a wire combing partition 123 is arranged between two adjacent sections.

[0067] In some embodiments of the present application, the flexible cutting tube 120 is a braided tube.

[0068] In some embodiments of the present application, the flexible cut tube 120 is a spiral cut tube.

[0069] In other embodiments of the present application, the flexible cutting tube 120 includes a braided tube and a spiral cutting tube, and the spiral cutting tube is sleeved on the outside of the braided tube. Optionally, the flexible cutting tube 120 can also be other flexible pipes, which is not limited in the present application.

[0070] In some embodiments of the present application, a protective cover is provided on the outside of the endoscope, the flexible cutting tube and the flexible hinge. By providing the protective cover to isolate the endoscope from the patient, only the protective cover needs to be replaced between two surgeries, and the instrument does not need to be sent out for sterilization, thereby improving the use efficiency of the endoscope.

[0071] In some embodiments of the present application, see Figure 1 and Figure 7 The transoral surgical endoscope system further comprises a laryngoscope support 201, to which a tongue depressor 202 is detachably connected. The laryngoscope support 201 and the tongue depressor 202 are provided with one or more channels for the endoscope 400 to pass through.

[0072] See also Figure 1 , Figure 1 The schematic diagram of the use state of the transoral surgical endoscope system provided in the present application shows that when performing transoral surgery, the endoscope 400 is first mounted on the endoscope fixing bracket 110 in the endoscope bracket 100, the tongue depressor structure 200 (including the endoscope fixing bracket 110 and the laryngoscope bracket 201) is mounted on the mechanical arm 300, and the tongue depressor 202 is mounted on the laryngoscope bracket 201. The endoscope can pass through the through holes on the laryngoscope bracket 201 and the tongue depressor 202 and extend into the patient's oral cavity for surgery. The tongue depressor 202 is disposable and is detachably connected to the laryngoscope bracket 201, so it is easy to replace after use.

[0073] In some embodiments of the present application, the endoscope 400 can be selected specifically according to the actual surgical situation, which is not limited in the present application.

[0074] In some embodiments of the present application, see Figure 7 The tongue depressor 202 is provided with a slot 204, and the laryngoscope support 201 is provided with a tongue depressor lock 203, which is detachably connected to the slot 204. By means of the slot 204 and the lock, the tongue depressor 202 can be quickly installed and removed, so that the tongue depressor 202 is easy to replace.

[0075] In some embodiments of the present application, see Fig.10 One end of the tongue depressor lock 203 is provided with a clamping portion 211 that cooperates with the clamping slot 204, and the other end is provided with a hand buckle portion 210. The middle part of the tongue depressor lock 203 is hinged to the laryngoscope bracket 201 through a hinge shaft 212. A compression spring 213 is provided between the tongue depressor lock 203 and the laryngoscope bracket 201, and the compression spring 213 is located between the clamping portion 211 and the hinge shaft 212.

[0076] When installing the tongue depressor 202, the tongue depressor 202 is pressed against the laryngoscope bracket 201, and the clamping portion 211 rotates around the hinge shaft 212 under the pressure of the tongue depressor 202, and finally is clamped into the clamping slot 204. The compression spring 213 can apply a force to the tongue depressor lock 203 to prevent the clamping portion 211 from escaping from the clamping slot 204, thereby preventing the tongue depressor 202 from loosening. When the tongue depressor 202 needs to be removed, the hand buckle 210 is moved outward by fingers to rotate the tongue depressor 202 buckle in the opposite direction, and the clamping portion 211 is disengaged from the clamping slot 204, thereby removing the tongue depressor 202. When the hand buckle 210 is pressed, the connection between the clamping portion 211 and the clamping slot 204 is more tightly, and the use of this structure can prevent the tongue depressor 202 from accidentally falling off due to the tongue depressor 202 buckle being accidentally pressed during use.

[0077] In some embodiments of the present application, see Fig.10 A limiting protrusion 214 is provided on one side of the tongue depressor lock 203 close to the laryngoscope bracket 201, and the limiting protrusion 214 abuts against the laryngoscope bracket 201 to limit the position of the clamping portion 211. The limiting protrusion 214 is located near the hinge shaft 212 and abuts against the laryngoscope bracket 201, which can prevent the clamping portion 211 from rotating too much under the elastic force of the compression spring 213, so as to facilitate the connection between the tongue depressor 202 and the tongue depressor lock 203.

[0078] In some embodiments of the present application, a handle (not shown in the figure) is connected to the laryngoscope bracket 201, and when the tongue depressor 202 is engaged with the laryngoscope bracket 201, the hand buckle portion 210 does not protrude from the surface of the handle.

[0079] The hand buckle 210 does not protrude from the surface of the handle, which can prevent the hand buckle 210 from being hooked up due to an operation error during surgery, causing the tongue depressor 202 to fall off. When the hand buckle 210 is pressed by mistake, the clamping portion 211 is more tightly connected to the clamping slot 204, and there is no risk of the tongue depressor 202 falling off. In some embodiments of the present application, the channels provided on the laryngoscope support 201 and the tongue depressor 202 include one or more of the flexible instrument channel 206, the endoscope channel 205, the auxiliary endoscope channel 207, the smoking channel 209, and the sputum suction channel.

[0080] In one embodiment of the present application, see Figure 7-Figure 9The channels arranged on the laryngoscope support 201 and the tongue depressor 202 include two flexible instrument channels 206, an endoscope channel 205, an auxiliary endoscope channel 207 and a smoking channel 209. The flexible instrument channel 206 is used for inserting flexible instruments to perform surgical operations. The endoscope channel 205 is used for inserting an endoscope to observe lesions. The auxiliary endoscope channel 207 is used for inserting an auxiliary endoscope. When in use, the auxiliary endoscope is set in the sleeve (flexible cutting tube 120 and flexible hinge 130), and then the sleeve and the auxiliary endoscope are inserted into the auxiliary endoscope channel 207 together. The auxiliary endoscope can add a new viewing angle to broaden the operating field of view during surgery (the field of view of the auxiliary endoscope 216 is as shown in FIG. Fig.11 As shown in the figure, the positional relationship between the lesion, the surrounding blood vessels, nerves and adjacent organs can be clearly seen at the same time, reducing the risk of damaging important tissues by misoperation. The smoking channel 209 is used to exhaust the smoke generated by the operation. The endoscope channel 205 is located in the middle of the tongue depressor 202, and the two flexible instrument channels 206 are located on both sides of the endoscope channel 205.

[0081] In some embodiments of the present application, the auxiliary endoscope adopts a xion endoscope. In other embodiments of the present application, the auxiliary endoscope may also adopt a wide-angle lens, a fisheye lens, etc., so as to significantly expand the viewing angle without increasing the physical size of the endoscope, allowing the doctor to obtain more surgical area information at one time.
