Description

TECHNICAL FIELD

[0001] The utility model relates to a kind of stretchable blunt plus sharp electrocoagulation blood vessel tissue dissectors for adhesion operation, belong to medical instrument technical field. BACKGROUND

[0002] Due to the increase of treatment means such as inflammation, tuberculosis, trauma and chemotherapy, radiotherapy, targeted therapy and immunotherapy of malignant tumors, there are more and more patients with pleural adhesion at present, the operation time of the patients with adhesion is long, there is much bleeding, postoperative complications are common, the probability of secondary operation increases, and it needs to be seriously faced.

[0003] At present, pleural adhesion is mainly treated by energy platform, and there are two commonly used: ultrasonic knife and high-frequency electrotome. The advantages of ultrasonic knife and its consumable system such as ultrasonic knife head are good hemostatic effect and less smoke, especially for blood vessels below 5mm and adhesion strips, and the disadvantages are slow cutting speed and no advantage for diffuse and dense adhesion; high-frequency electrotome system has fast cutting speed, but has poor hemostatic effect on adhesion containing small blood vessels, produces more smoke, resulting in unclear operation field, and the two have poor separation and hemostatic effect on diffuse and dense adhesion, especially in the chest wall.

[0004] Side chest wall adhesion is more difficult to handle, and its characteristics are: the position is hidden, and it is difficult to find under open and endoscopic operation; it is not easy to separate after being found, and it is not easy to stop bleeding after being separated, which is the most difficult position to handle in the operation of thoracic surgeons. Side chest wall adhesion can be near the incision, can be at the costophrenic angle, and of course lung door, chest top, interlobar and other parts can be the parts where adhesion often occurs. In the process of treatment, blunt and sharp separation techniques need to be combined, blunt separation often needs suction, sharp separation often needs electrotome, electric hook and other instruments. These adhesions, due to the difference of shape, toughness, thickness, size, volume and position, need different instruments and surgical incisions to handle, so as to achieve complete adhesion separation, facilitate operation and shorten operation time, and the purpose of less bleeding. However, there is currently a lack of instruments for treating adhesion with "blunt plus sharp" technology, especially for side chest wall adhesion. SUMMARY

[0023] Example

[0024] This embodiment provides a retractable blunt-sharp electrocoagulation vascular tissue dissector for adhesion surgery, such as... Figures 1-4 As shown, the package includes a handle 3, a conductive blunt-tipped electrosurgical tube 6, and a conductive hook. The conductive blunt-tipped electrosurgical tube 6 is a stainless steel tube wrapped with an insulating sleeve 5. One end has a suction tube connector 2, and the other end has an exposed, rounded, blunt-faced metal opening. The end of the conductive blunt-tipped electrosurgical tube 6 with the suction tube connector 2 passes through the inner cavity of the handle 3, and the suction tube connector 2 protrudes outside the handle 3. The suction tube connector 2 is used to connect to a negative pressure suction device. A plug 1 for connecting to the electrosurgical unit is also provided on one side of the handle 3. The conductive hook includes a hook tube body 10 and a hook portion 7. The hook tube body 10 of the conductive hook is slidably connected to the cavity of the conductive blunt-tipped electrosurgical tube 6. The handle 3 is provided with a push-out mechanism for operating the extension and retraction of the hook tube body 10 relative to the conductive blunt-tipped electrosurgical tube 6 to push out or retract the hook portion 7. Figure 1 The diagram shows the retraction of the electric hook into the conductive blunt-tipped electrosurgical tube 6. Figure 2 and Figure 3 The diagram shown is a schematic of the extension of the electric hook 7.

[0025] In this embodiment, the insulating sleeve 5 is made of insulating material PEEK;

[0026] In this embodiment, the internal structure of the handle is as follows: Figures 3-4As shown, the inner cavity of the handle 3 is provided with a wire 8 for connecting the electric plug 1 and the conductive blunt electric knife tube 6 and the conductive electric hook, and the connection mode is welding. The push-out mechanism comprises a push-out switch 4 which is slidably connected to the shell of the handle 3, and the push-out switch 4 is provided with a sliding block 9, the sliding block 9 is connected to the conductive blunt electric knife tube 6 and the electric hook tube body 10, the connection mode between the sliding block 9 and the conductive blunt electric knife tube 6 is a sliding pair, the sliding block 9 slides on the conductive blunt electric knife tube, and the sliding block 9 is connected to the electric hook tube body 10 by means of a screw 11. The push-out switch 4, the sliding block 9, the screw 11 and the conductive electric hook form an integral whole, and the push-out and retraction of the conductive electric hook are controlled by the push-out switch 4. Among them, the shape and angle of the hook head of the electric hook part 7 can be designed in various ways, and the size of the hook head should be designed to be capable of being accommodated in the tube body of the conductive blunt electric knife tube 6, that is, capable of being retracted in the tube body of the conductive blunt electric knife tube 6.

[0027] In the embodiment, the exposed part of the conductive blunt electric knife tube 6 is provided with a limiting hole 12 for preventing the conductive electric hook from retracting after being pushed out, and the position close to the electric hook part of the conductive electric hook is correspondingly provided with a protrusion (not shown in the figure) for being clamped in the limiting hole 12, and the protrusion can be a semispherical protrusion with a circular arc surface (low at both ends and high in the middle (protrusion)) or a protrusion with a wedge surface (low at the end close to the sliding switch and high at the end close to the electric hook part (protrusion)), so that when the electric hook part is retracted by pulling the push-out switch, the lower end of the protrusion can pass through the limiting hole 12 to release the limiting, and when the electric hook part 7 needs to be pushed out by pushing the push-out switch, the higher end of the protrusion (one end of the protrusion) can be clamped in the limiting hole 12, so as to facilitate the fixation of the electric hook part 7 and prevent the electric hook part 7 from retracting by sliding during the operation.

[0028] The working principle of the above-mentioned electric coagulation vessel tissue stripper:

[0029] When the electric plug 1 is connected to the electric knife main machine (the electric knife main machine is prior art, not shown in the figure), the exposed part of the conductive blunt electric knife tube 6 is electrified to perform blunt cutting or stripping, which is mainly used for cutting coagulation, adhesion and blood vessel separation. The push-out switch 4 provided on the handle 3 is used to push and pull the conductive electric hook in the lumen of the conductive blunt electric knife tube 6 to expose the electric hook part 7; when electric coagulation and suction are needed, the conductive electric hook is pulled back, and the suction tube connector 2 is connected to the negative pressure suction device to perform electric coagulation and suction; when the conductive electric hook is needed, the conductive electric hook is pushed out to cut the tissue sharply, so as to form the combined advantages of "blunt plus sharp".

[0030] The above-mentioned embodiment is only a preferred embodiment of the present application, and does not limit the present application in any form and in essence. It should be pointed out that for ordinary skilled persons in the art, some improvements and supplements can be made without departing from the present application, and these improvements and supplements should also be regarded as the protection scope of the present application.
