Description

Technical Field

[0001] The utility model relates to the technical field of medical instruments, in particular to an ultrasonic probe fixing device for percutaneous tracheotomy. Background Art

[0002] Ultrasound examination has been widely used in the intensive care unit (ICU). The use of ultrasound examination to assist minimally invasive percutaneous tracheotomy can improve the safety of minimally invasive percutaneous tracheotomy. Before surgery, ultrasound examination can be used to select the puncture site and avoid damaging surrounding blood vessels. During surgery, ultrasound examination can be used as a real-time guide for the puncture site and monitor the location of the tracheotomy. Tracheotomy is generally selected below the first cartilage ring or below the second cartilage ring. This position is safer. Tracheotomy between the cricoid cartilage and the first cartilage ring has more sequelae. The use of ultrasound examination can avoid tracheotomy here.

[0003] However, when performing a tracheotomy, the surgeon stands on the right side of the patient, fixes the patient's trachea with his left hand, and performs the operation with his right hand. If ultrasound guidance is used, an assistant is required to hold the ultrasound probe. Unlike ultrasound-guided vascular puncture, ultrasound-guided tracheotomy puncture uses an out-of-plane puncture technique, and it is sometimes difficult to keep the entire puncture needle in the plane. However, when someone else is holding the ultrasound probe for guidance, real-time dynamic observation and adjustment are even more difficult. It is very difficult for two people to coordinate the puncture needle and ultrasound probe separately, and they cannot work effectively.

[0004] The existing patent CN215503113U discloses an ultrasonic probe fixing device for percutaneous tracheotomy, which solves the problem that the surgeon stands on the right side of the patient, fixes the patient's trachea with his left hand and performs the operation with his right hand, while another person holds the ultrasonic probe to guide, and the two people separately control the puncture needle and the ultrasonic probe, which makes it difficult for them to coordinate and work effectively.

[0005] However, the ultrasonic probe fixing device for percutaneous tracheotomy in the patent has a complex connection structure between the ultrasonic probe and the main frame, and both connection and disassembly are inconvenient, which increases the instrument preparation time before surgery and the instrument arrangement time after surgery.

[0006] Therefore, there is an urgent need for an ultrasonic probe fixing device for percutaneous tracheotomy to solve the above problems. Utility Model Content

In addition, the terms "first" and "second" are only used to distinguish in the description and have no special meaning.

[0056] like Figure 1-4 As shown, this embodiment provides an ultrasonic probe fixing device for percutaneous tracheotomy, including a neck fixing frame 1, a main frame 2, an ultrasonic probe 3 and a puncture needle guide frame 4. A connecting portion 21 is provided on one side of the main frame 2, and the connecting portion 21 is connected to the neck fixing frame 1. A mounting groove is provided on the top of the main frame 2, and the bottom of the ultrasonic probe 3 is inserted into the mounting groove. The side walls on both sides of the mounting groove are provided with limiting through holes 22. The bottom of the ultrasonic probe 3 is provided with a limiting component 31 corresponding to the limiting through holes 22. When the bottom of the ultrasonic probe 3 is inserted into the mounting groove, the limiting component 31 extends into the corresponding limiting through hole 22 to connect the ultrasonic probe 3 and the main frame 2. The limiting component 31 can be extended and retracted along the extension direction of the limiting through hole 22, so that the ultrasonic probe 3 can be removed from the mounting groove. The puncture needle guide frame 4 is fixedly arranged on the main frame 2.

[0057] The ultrasonic probe fixing device for percutaneous tracheotomy provided in this embodiment is connected to the patient's neck through the neck fixing frame 1, which not only supports the ultrasonic probe 3, but also fixes the patient's neck to avoid shaking of the patient's neck during operation and ensure that the trachea does not move. The puncture needle is supported and guided by the puncture needle guide frame 4, which makes it convenient for the surgeon to operate the ultrasonic probe 3 and the puncture needle for tracheotomy puncture while fixing the patient's neck. The ultrasonic probe 3 is plugged into the main frame 2 and connected through a limit assembly 31. The limit assembly 31 is retractable. When installing the ultrasonic probe 3, the ultrasonic probe 3 is inserted into the mounting slot on the main frame 2 by compressing the limit assembly 31. After the ultrasonic probe 3 is plugged into place, the limit assembly 31 extends into the corresponding limit through hole 22 to connect the ultrasonic probe 3 to the main frame 2. When it is necessary to remove the ultrasonic probe 3, the limit assembly 31 is compressed by fingers to make the limit assembly 31 leave the limit through hole 22, so that the ultrasonic probe 3 can be pulled out of the mounting slot. Both installation and removal are very quick and fast, which effectively saves the instrument preparation time before the operation and the instrument sorting time after the operation.

[0058] Alternatively, if Figure 1-4 As shown, the limiting assembly 31 includes a support block 311, a support plate 312, a slide bar 313, a support spring 314 and a positioning plate 315. One end of the support block 311 is fixedly arranged on the side of the ultrasonic probe 3, and the other end is provided with a receiving groove. The support plate 312 is fixedly arranged in the receiving groove, and a connecting hole is arranged on the support plate 312. The slide bar 313 is slidably arranged in the connecting hole, and the end of the slide bar 313 away from the bottom of the receiving groove is provided with a first limiting plate 3131, and the cross-sectional size of the first limiting plate 3131 is larger than the connecting hole. The support spring 314 is sleeved on the slide bar 313, and one end abuts against the support plate 312, and the other end abuts against the first limiting plate 3131. The positioning plate 315 is arranged on the first limiting plate 3131, and the positioning plate 315 can extend into the limiting through hole 22. The slide bar 313 can slide relative to the support plate 312, and the support spring 314 abuts between the first limit plate 3131 on the slide bar 313 and the support plate 312, so that the first limit plate 3131 and the positioning plate 315 arranged on the first limit plate 3131 can be extended and retracted along the extension direction of the limit through hole 22. When the ultrasonic probe 3 is installed in the accommodating groove, the positioning plate 315 extends into the limit through hole 22. The arrangement of the first limit plate 3131 can prevent the slide bar 313 from completely sliding into between the support plate 312 and the bottom of the accommodating groove.

[0059] Furthermore, if Figure 1-4As shown, the limiting assembly 31 further includes a connecting block 316 and a stud 317. The connecting block 316 is fixedly arranged on a side of the positioning plate 315 close to the bottom of the receiving groove, and a threaded hole is arranged on the connecting block 316. The stud 317 is fixedly arranged on a side of the first limiting plate 3131 away from the sliding rod 313, and one end of the stud 317 away from the positioning plate 315 extends into the threaded hole of the connecting block 316 and is threadedly connected to the connecting block 316. The connecting block 316 and the stud 317 realize a detachable connection between the positioning plate 315 and the first limiting plate 3131.

[0060] Furthermore, if Figure 1-4 As shown, a second limit plate 3132 is fixedly arranged at the end of the slide bar 313 near the bottom of the receiving groove, and the cross-sectional size of the second limit plate 3132 is larger than the connecting hole. The second limit plate 3132 is arranged to prevent the slide bar 313 from completely sliding out of the support plate 312.

[0061] Alternatively, if Figure 1 As shown, the neck fixing frame 1 includes a C-shaped frame 11, a support rod 12, a first adjustment frame 13 and a second adjustment frame 14. The support rod 12 is fixedly arranged on the top of the C-shaped frame 11, and the support rod 12 divides the C-shaped frame 11 into a left frame 111 and a right frame 112. The left frame 111 is provided with a first adjustment frame 13 that can slide along the track direction of the left frame 111. The right frame 112 is provided with a second adjustment frame 14 that can slide along the track direction of the right frame 112. Through the sliding of the first adjustment frame 13 relative to the left frame 111, and the sliding of the second adjustment frame 14 relative to the right frame 112, the width of the neck fixing frame 1 can be adjusted so that the neck fixing frame 1 can be suitable for patients with different sizes of necks.

[0062] Furthermore, if Figure 1As shown, the neck fixing frame 1 also includes an adjustment assembly 15, which includes an adjustment rod 151, a first connecting rod 152 and a second connecting rod 153. A mounting hole coaxially arranged with the support rod 12 is provided in the support rod 12, and the bottom end of the adjustment rod 151 is slidably arranged in the mounting hole. The first connecting rod 152 is hinged at its bottom end to the first adjustment frame 13, and hinged at its top end to the adjustment rod 151. The second connecting rod 153 is hinged at its bottom end to the second connecting rod 153, and hinged at its top end to the adjustment rod 151. The hinge axis between the first connecting rod 152 and the first adjustment frame 13 is parallel to the hinge axis between the first connecting rod 152 and the adjustment rod 151, the hinge axis between the second connecting rod 153 and the second adjustment frame 14 is parallel to the hinge axis between the second connecting rod 153 and the adjustment rod 151, and the hinge axis between the first connecting rod 152 and the adjustment rod 151 is colinear with the hinge axis between the second connecting rod 153 and the adjustment rod 151. The first adjustment frame 13 and the second adjustment frame 14 are linked by the cooperation of the adjustment rod 151, the first connecting rod 152 and the second connecting rod 153, so that the first adjustment frame 13 and the second adjustment frame 14 can maintain symmetry about the support rod 12 before and after adjustment, thereby ensuring the stability of the connection between the ultrasonic probe fixing device for percutaneous tracheotomy and the patient's neck.

[0063] Furthermore, if Figure 1 As shown, both sides of the support rod 12 are provided with a clearance hole 121 connecting the outer side of the support rod 12 and the mounting hole, and the clearance hole 121 extends along the axial direction of the support rod 12. The top end of the first connecting rod 152 passes through the clearance hole 121 on one side of the support rod 12 and is hinged to the adjustment rod 151, and the top end of the second connecting rod 153 passes through the clearance hole 121 on the other side of the support rod 12 and is hinged to the adjustment rod 151. The first connecting rod 152 and the second connecting rod 153 can be extended into the support rod 12 and hinged to the adjustment rod 151 by providing the clearance hole 121.

[0064] Furthermore, if Figure 1As shown, the adjustment assembly 15 further includes a first adjustment nut 154 and a second adjustment nut 155. The adjustment rod 151 is provided with an external thread, and the first adjustment nut 154 is sleeved on the adjustment rod 151 and is threadedly connected to the adjustment rod 151. The support rod 12 is provided with an external thread, and the second adjustment nut 155 is sleeved on the support rod 12 and is threadedly connected to the support rod 12, and the top end of the second adjustment nut 155 is fixedly connected to the bottom end of the first adjustment nut 154, the pitch of the external thread on the support rod 12 is greater than the pitch of the external thread on the adjustment rod 151, and the external thread on the support rod 12 and the external thread on the adjustment rod 151 have the same rotation direction. Since the pitch of the external thread on the support rod 12 is greater than the pitch of the external thread on the adjusting rod 151, and the first nut and the second nut are fixedly connected, the first nut and the second nut rotate together the same number of turns, and the stroke of the second nut relative to the support rod 12 along the axial direction of the support rod 12 is greater than the stroke of the first nut relative to the adjusting rod 151 along the axial direction of the adjusting rod 151. Therefore, by rotating the first nut and the second nut, the adjusting rod 151 can be driven to slide relative to the support rod 12, and then the first adjustment frame 13 and the second adjustment frame 14 can be driven to slide relative to the C-shaped bracket 11 to adjust the width of the neck fixing frame 1.

[0065] Furthermore, if Figure 1 As shown, a connection hole is provided on the connection part 21, and the support rod 12 is slidably inserted into the connection hole, and the adjustment assembly 15 also includes a third adjustment nut 156 and a fourth adjustment nut 157. The third adjustment nut 156 is sleeved on the support rod 12 and is threadedly connected to the support rod 12, and the third adjustment nut 156 is located above the connection part 21. The fourth adjustment nut 157 is sleeved on the support rod 12 and is threadedly connected to the support rod 12, and the fourth adjustment nut 157 is located below the connection part 21. The third adjustment nut 156 and the fourth adjustment nut 157 cooperate to support and fix the connection part 21, so as to prevent the main frame 2 from sliding relative to the neck fixing frame 1 during the use of the ultrasonic probe fixing device for percutaneous tracheotomy. Furthermore, by rotating the fourth adjusting nut 157 to move the fourth adjusting nut 157 downward, then sliding the connecting part 21 downward, and finally rotating the third adjusting nut 156 to move the third adjusting nut 156 downward, the main frame 2 can be moved downward. Similarly, by rotating the third adjusting nut 156 to move the third adjusting nut 156 upward, then sliding the connecting part 21 upward, and finally rotating the fourth adjusting nut 157 to move the fourth adjusting nut 157 upward, the main frame 2 can be moved upward, which is convenient for medical personnel to adjust the height of the ultrasound probe 3 as needed.

[0066] Furthermore, a groove extending along the axial direction of the support rod 12 is provided on the outer wall of the support rod 12, and a protrusion cooperating with the groove is provided on the inner wall of the connecting hole, and the protrusion is inserted into the groove. The cooperation between the protrusion and the groove prevents the main frame 2 from rotating relative to the neck fixing frame 1 during the use of the ultrasonic probe fixing device for percutaneous tracheotomy.

[0067] The ultrasonic probe fixing device for percutaneous tracheotomy provided in this embodiment can effectively fix the patient's neck, making operations such as puncture needle puncture more convenient. The use of ultrasonic guidance can help determine the position of the tracheotomy tube (deep or shallow), clarify whether the puncture needle has entered the airway, and confirm the position of the guide wire; help monitor the dilator, help find the position of the cartilage ring, avoid damaging the side wall and posterior wall of the trachea to cause esophageal tracheal fistula, and reduce the risk of damage to the posterior wall of the airway. In addition, the installation and disassembly between the ultrasonic probe 3 and the main frame 2 are very quick and convenient, and the height of the ultrasonic probe 3 and the width of the neck fixing frame 1 can be adjusted.

[0068] The above is only a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and substitutions can be made without departing from the technical principle of the present invention. These improvements and substitutions should also be regarded as the protection scope of the present invention.
