Description

Technical Field

[0001] The utility model relates to the technical field of medical surgical instruments, in particular to a medical skull base surgical separation forceps with the function of early warning the position of the internal carotid artery by Doppler ultrasound. Background Art

[0002] In current skull base tumor surgery, CT scans are first used to check the location of the tumor. The surgeon then makes a hole in the patient's head and neck, and with the help of a tiny light source and a tiny camera, inserts a separation forceps into the hole. The forceps are operated to separate and peel off the surrounding muscle and other tissues to find the tumor at the skull base. During the search for the tumor, the surgeon uses the ultrasonic probe of a transcranial Doppler ultrasound diagnostic instrument to insert the ultrasonic probe into the hole to detect the blood vessels of the internal carotid artery to prevent damage to the artery when operating the separation forceps, causing heavy bleeding. After finding the tumor at the skull base, a scalpel is used to remove the tumor.

[0003] Transcranial Doppler ultrasound diagnostic instrument is a non-invasive ultrasound detection technology that uses the weak parts of the skull as the examination sound window and applies the Doppler effect to study the hemodynamics of the cerebral basilar arteries.

[0004] Due to the small operating space of the channel, it is not advisable to insert too many surgical instruments at the same time. The surgical instruments will interfere with each other in the channel and affect the operation. The surgeon uses the separation forceps and ultrasonic probe to insert the two instruments alternately into the channel. When using the ultrasonic probe to detect the tissue in the channel, the surgeon checks the transcranial Doppler ultrasound diagnostic instrument to determine whether the internal carotid artery is touched. When the ultrasonic probe touches the internal carotid artery, the location of the internal carotid artery is determined, and the separation forceps are used to bypass the internal carotid artery, and then separate and peel the surrounding muscles and other tissues; when the ultrasonic probe does not touch the internal carotid artery, the surgeon operates the separation forceps to directly separate and peel the surrounding muscles and other tissues. Each time the separation forceps are operated, they must move slightly forward in the channel to separate the muscles and other tissues, and then replace the ultrasonic probe to avoid damaging the internal carotid artery in the process of searching for skull base tumors. However, the operation of the separation forceps and ultrasonic probes alternately inserting the two instruments into the channel is very cumbersome, and the efficiency of searching and removing skull base tumors is low.

[0005] Therefore, how to combine an ultrasonic probe with a separation forceps to detect the internal carotid artery in real time during the process of separating and peeling the skull base tissue is a technical problem that urgently needs to be solved in the current field. Utility Model Content

[0030] The utility model provides a medical skull base surgical separation forceps with the function of Doppler ultrasound early warning of the position of the internal carotid artery, which overcomes the disadvantage of the background technology that the surgeon uses the separation forceps and the ultrasonic probe to alternately extend the two instruments into the channel, which is cumbersome to operate; the ultrasonic probe is combined with the separation forceps, and the internal carotid artery is detected in real time during the process of separating and peeling the skull base tissue, thereby improving the technical effect of finding and removing skull base tumors.

[0031] The overall idea of ​​the technical solution of the embodiment of the utility model is as follows:

[0032] The ultrasonic probe is fixedly arranged at the head end of the first clamp part, and the ultrasonic probe is connected to the socket through a first wire. The first wire is attached to the surface of the first clamp part, passes through the left end of the long tube, and is attached to the surface of the long tube. The socket is located on the right end surface of the long tube. When the utility model is used, the plug is inserted into the socket to connect the ultrasonic probe to the transcranial Doppler ultrasonic diagnostic instrument. When the utility model is not in use, the plug is pulled out from the socket to facilitate transportation and cleaning and disinfection of the instrument.

[0033] When it is necessary to find a skull base tumor, the clamp of the utility model is inserted into the hole, and the ultrasonic probe located at the head end of the clamp contacts the skull base tissue. When the transcranial Doppler ultrasonic diagnostic instrument detects the internal carotid artery through the ultrasonic probe, the transcranial Doppler ultrasonic diagnostic instrument controls the alarm to send a signal to remind the operating personnel, and the operating personnel change the position of the clamp, bypass the internal carotid artery, and then operate the clamp to separate and peel the surrounding muscles and other tissues; in the process of separating and peeling the skull base tissue, the ultrasonic probe detects in real time whether it touches the internal carotid artery. When the transcranial Doppler ultrasonic diagnostic instrument does not detect the internal carotid artery through the ultrasonic probe, the operating personnel operate the clamp to directly separate and peel the surrounding muscles and other tissues to continue to find the skull base tumor.

[0034] In order to better understand the above technical solution, the above technical solution will be described in detail below in conjunction with the accompanying drawings and specific implementation methods.

[0035] See also Figures 1 to 9 , a preferred embodiment of the utility model.

[0036] A medical skull base surgical separation forceps with Doppler ultrasound early warning function of the internal carotid artery position, comprising:

[0037] A separation forceps device 1 and a Doppler ultrasound early warning device 2;

[0038] The separation clamp device 1 comprises a first clamp part 11, a second clamp part 12, a long tube 13 and a pin 14, wherein the first clamp part 11 and the second clamp part 12 are hingedly connected via the pin 14, and the pin 14 is fixedly arranged at the left end of the long tube 13;

[0039] The Doppler ultrasound early warning device 2 includes an ultrasound probe 21, a transcranial Doppler ultrasound diagnostic instrument 22, an alarm 23, a first wire 24, a second wire 25, a third wire 26, a plug 27 and a socket 28. The ultrasound probe 21 is fixedly arranged at the head end of the first clamp 11, and the ultrasound probe 21 is connected to the socket 28 through the first wire 24. The first wire 24 is attached to the surface of the first clamp 11, passes through the left end of the long tube 13, and is then attached to the surface of the long tube 13. The socket 28 is fixedly arranged on the right end surface of the long tube 13, the plug 27 is connected to the transcranial Doppler ultrasound diagnostic instrument 22 through the second wire 25, the transcranial Doppler ultrasound diagnostic instrument 22 is connected to the alarm 23 through the third wire 26, and the plug 27 is inserted into the socket 28.

[0040] In the utility model, the ultrasonic probe 21 is located at the head end of the clamp. During the skull base tumor surgery, the surgeon inserts the clamp of the utility model into the channel 3. When the head end of the clamp contacts the skull base tissue, the alarm 23 sends a signal, indicating that the internal carotid artery 31 is touched. The surgeon changes the position of the clamp to bypass the internal carotid artery 31 and then operates the clamp to separate and peel the surrounding tissue. When the alarm 23 does not send a signal, indicating that the internal carotid artery 31 is not touched, the surgeon operates the clamp to directly separate and peel the surrounding muscle and other tissues. There is no need to alternately use the separation clamp and the ultrasonic probe 21 in the background technology to insert into the channel 3. The utility model combines the ultrasonic probe 21 with the separation clamp, and in the process of separating and peeling the skull base tissue, the internal carotid artery 31 is detected in real time, thereby improving the efficiency of searching and removing the skull base tumor 32.

[0041] A wire groove is provided on the surface of the long tube 13, and the first wire 24 is built in the wire groove. The beneficial effect of this technical solution is that the first wire 24 is not exposed on the surface of the long tube 13, which effectively prevents the first wire 24 from being damaged.

[0042] The separating forceps device 1 further comprises a forceps frame 15 and a hand wheel 16, wherein the hand wheel 16 is fixedly arranged on the right end surface of the long tube 13, and the hand wheel 16 is also connected to the forceps frame 15 by threaded locking, and the socket 28 is fixedly arranged on the surface of the hand wheel 16. The beneficial effect of this technical solution is that it is convenient for the surgeon to fix the long tube 13 on the forceps frame 15 by operating the hand wheel 16.

[0043] The alarm 23 is a speaker. The beneficial effect of this technical solution is that when the transcranial ultrasound Doppler diagnostic instrument detects the internal carotid artery 31 through the ultrasound probe 21, it sends a signal to the speaker, and the speaker reminds the operating personnel, so that the operating personnel can focus more on operating the separation and closure of the first clamp part 11 and the second clamp part 12, and moving the positions of the first clamp part 11 and the second clamp part 12 to avoid the internal carotid artery 31.

[0044] The separating clamp device 1 also includes a first connecting rod 17, a second connecting rod 18, a slider 19, a pull rod 110 and a support 111. The left end of the first connecting rod 17 is hinged to the tail end of the first clamp part 11, the right end of the first connecting rod 17 is hinged to the slider 19, the left end of the second connecting rod 18 is hinged to the tail end of the second clamp part 12, the right end of the second connecting rod 18 is hinged to the slider 19, the slider 19 is fixedly connected to the left end of the pull rod 110, the pull rod 110 is slidably connected to the through hole of the support 111, the support 111 is fixedly connected to the inner wall of the long tube 13, and the pull rod 110 is also slidably connected to the channel of the clamp frame 15. The beneficial effect of this technical solution is that when the pull rod 110 slides to the left, the angle between the first connecting rod 17 and the tail end of the first jaw 11 becomes smaller, the angle between the second connecting rod 18 and the tail end of the second jaw 12 becomes smaller, the head end of the first jaw 11 and the head end of the second jaw 12 are opened, and the operation of separating and peeling off muscle and other tissues can be performed; when the pull rod 110 slides to the right, the angle between the first connecting rod 17 and the tail end of the first jaw 11 becomes larger, the angle between the second connecting rod 18 and the tail end of the second jaw 12 becomes larger, and the head end of the first jaw 11 and the head end of the second jaw 12 are closed.

[0045] The separating pliers device 1 also includes a first handle 112, a second handle 113, a torsion spring 114, a concave plate 115 and a nut 116. The right end of the pull rod 110 passes through the notch of the concave plate 115. The nut 116 is locked and connected to the right end of the pull rod 110. The two nuts 116 are respectively on the left and right sides of the concave plate 115. The first handle 112 is fixedly connected to the pliers frame 15. The second handle 113 is hinged to the pliers frame 15. The bottom of the concave plate 115 is fixedly connected to the second handle 113. The torsion spring 114 is installed between the first handle 112 and the second handle 113. The beneficial effect of this technical solution is that the surgeon's fingers hold the first handle 112 and the second handle 113, and then operate the second handle 113 to drive the concave plate 115, so that the pull rod 110 moves to the right. At this time, the torsion spring 114 is in a torsion state. When the second handle 113 is released, the torsion spring 114 is reset, and the concave plate 115 causes the pull plate to move to the left.

[0046] Working mode of the utility model:

[0047] During the skull base tumor surgery, the first clamp 11 and the second clamp 12 of the present invention are inserted into the pre-made channel 3. When the head end of the first clamp 11 contacts the skull base tissue in the channel 3, the ultrasonic probe 21 also contacts the skull base tissue. At this time, the transcranial Doppler ultrasound diagnostic instrument 22 detects whether it touches the internal carotid artery 31. When it touches the internal carotid artery 31, the alarm 23 generates a warning signal to remind the operating staff to change the position of the first clamp 11 and the second clamp 12, bypass the internal carotid artery 31, and then operate the first handle 112 and the second handle 113 to control the first clamp 11 and the second clamp 12 to separate and peel the surrounding tissue, so as to achieve the purpose of warning the position of the internal carotid artery and avoid damaging the internal carotid artery 31. When the ultrasonic probe 21 continues to contact the skull base tissue in the channel 3, when it does not touch the internal carotid artery 31, the alarm 23 does not generate a warning signal, and the operating staff operates the first handle 112 and the second handle 113 to control the first clamp to directly separate and peel the surrounding muscle and other tissues, and continue to search for the skull base tumor 32. After the tumor 32 located at the skull base is found, the tumor 32 is removed using a scalpel.

[0048] Although the specific implementation methods of the present invention are described above, those skilled in the art should understand that the specific embodiments described are only illustrative and are not intended to limit the scope of the present invention. Equivalent modifications and changes made by those skilled in the art in accordance with the spirit of the present invention should be included in the scope of protection of the claims of the present invention.
