Description

Technical Field

[0001] The present invention relates to the technical field of surgical tools, and particularly to a new type of rapid bloodless tracheotomy portable ultrasonic scalpel. Background Art

[0002] Some critically ill, complex combat trauma, and mass injury patients often face difficulty in breathing and require emergency tracheotomy to rescue their lives and ensure the smooth progress of subsequent series of first aid, especially during the rescue of mass injuries. These patients often have difficulties in trachea searching and exposure due to reasons such as extensive burns, neck swelling, cervical spine injuries, and short necks. It is difficult to cut the hard skin, and it is difficult to stop bleeding during the operation. All these will lead to a significant prolongation of the tracheotomy time and even the failure to complete the operation.

[0003] Brain tissue will suffer irreversible damage after 5 minutes of hypoxia. Whether tracheotomy intubation can be performed quickly and accurately is the key to determining the life and death of patients. Especially during the rescue of mass injuries, time is life.

[0004] Currently, tracheotomy usually uses a conventional surgical blade + hemostatic instrument (bipolar or monopolar electrocoagulation). For patients with normal neck structures and skilled doctors, with the assistance of an assistant, the operation can be completed in about 15 - 20 minutes. The hemostasis process is time-consuming, especially when the large thyroid gland in front of the trachea needs to be incised. The bipolar or monopolar electrocoagulation for hemostasis has a smaller blood vessel diameter (generally less than 3 mm), and there is a burnt tissue aerosol (operator injury), and at the same time, it will cause local tissue damage in the surgical area. Currently, the soft tissue ultrasonic scalpel has good hemostasis effect, and the coagulated blood vessel diameter is larger (generally less than 5 mm), but it cannot be used for skin incision and tracheal cartilage incision. The knife shapes are only scissor type and gun type, and it cannot be used for superficial tracheotomy. At the same time, the knife size is large and not easy to carry.

[0005] In order to save time, percutaneous puncture emergency tracheal intubation guided by a palm-sized ultrasonic device can also be used, but the problems it has include: (1) The completion time depends on the proficiency of the operator. Since this operation is not a routine clinical application, there are few skilled operators; (2) It belongs to blind intubation, unable to stop bleeding and prone to damage to the trachea and blood vessels; (3) The ultrasonic device can only display cross-sections and requires the assistance of an assistant (it cannot be operated alone during first aid). Summary of the Invention

[0006] The technical problem to be solved by the present invention is to provide an ultrasonic scalpel that can be bloodless or automatically stop bleeding during the operation; has a clear field of vision, avoids damage, and saves time; has multiple functions. In addition to cutting soft tissues and coagulating blood vessels, it can also cut the skin and tracheal cartilage, and can face multiple situations at the same time; is small and easy to carry.

[0007] The present invention relates to a rapid bloodless tracheotomy portable ultrasonic scalpel, which includes a blade head and a handle, and has an overall scalpel-like structure. The blade head includes a main blade and a secondary blade. The lower edge of the main blade is a sharp blade-like structure for cutting skin, soft tissue or cartilage. The upper edge of the main blade cooperates with the lower edge of the secondary blade to form scissors for closing blood vessels or cutting soft tissue. The front ends of the main blade and the secondary blade are both set as tips, which are aligned to form electrodes.

[0008] For the rapid bloodless tracheotomy portable ultrasonic scalpel of the present invention, a convex part and a concave part that can cooperate with each other are correspondingly arranged on the upper edge of the main blade and the lower edge of the secondary blade.

[0009] For the rapid bloodless tracheotomy portable ultrasonic scalpel of the present invention, the handle includes a main handle and a secondary handle, and the two handles are connected by a hinge.

[0010] For the rapid bloodless tracheotomy portable ultrasonic scalpel of the present invention, a main handle and a secondary handle are respectively installed on the main handle and the secondary handle.

[0011] For the rapid bloodless tracheotomy portable ultrasonic scalpel of the present invention, a transducer is arranged inside the main handle. The transducer is connected to a connecting wire, and the other end of the connecting wire is connected to a main unit.

[0012] For the rapid bloodless tracheotomy portable ultrasonic scalpel of the present invention, the blade head is installed on the handle or integrally formed with the handle.

[0013] The difference between the rapid bloodless tracheotomy portable ultrasonic scalpel of the present invention and the prior art is that the rapid bloodless tracheotomy portable ultrasonic scalpel of the present invention has three functions at the same time: a knife, scissors and bipolar electrocoagulation, which can be freely switched according to needs, achieving the effect of rapid cutting (skin, soft tissue and cartilage) and thorough hemostasis with one scalpel. The blade-like structure at the lower edge of the main blade can cut the skin, soft tissue and cartilage; the joint surface between the main blade and the secondary blade can coagulate thicker blood vessels (generally reliable below 5 mm) or cut soft tissue; the electrode at the tip of the front part of the blade head can timely perform hemostasis operations on small blood vessels in parts such as the anterior wall of the trachea and fascia.

[0014] The rapid bloodless tracheotomy portable ultrasonic scalpel of the present invention is relatively short, especially the blade head part is shorter, making it flexible for doctors to operate during the operation, not blocking the vision, effectively avoiding damage and saving operation time; at the same time, it is also relatively portable, convenient to carry and cooperate with different devices for use.

[0020] The following embodiments are used to illustrate the present invention, but are not used to limit the scope of the present invention.

[0021] Embodiment

[0022] As Figures 1 - 3 shown, the portable ultrasonic scalpel for rapid bloodless tracheotomy of the present invention includes a tool head and a handle. The tool head is installed on the handle, and the whole is in the structure of a scalpel. In other embodiments, the tool head can also be integrally formed with the handle. The two handles are closed into one body and are connected by a hinged bolt 3 at the front end. The tool head and the handle can rotate around the bolt 3, facilitating hemostasis and cutting of blood vessels and tissues in various directions during the operation.

[0023] The length of the tool head is 10 mm and it includes a main piece 2 and a secondary piece 1. The main piece 2 is located below the secondary piece 1. The lower edge of the main piece 2 is a sharp blade - type structure 9, which can be used to cut skin, soft tissue, and cartilage. The length of the blade is 5 mm. The upper edge of the main piece 2 cooperates with the lower edge of the secondary piece 1, and when closed, it has the effect of scissors. The scissors can reliably coagulate blood vessels less than 5 mm in diameter, and theoretically up to 7 mm at most, while cutting soft tissue.

[0024] Correspondingly arranged on the upper edge of the main piece 2 and the lower edge of the secondary piece 1 are a same number of protrusions 12 and grooves 11. When the main piece 2 and the secondary piece 1 are closed, the protrusions 12 and the grooves 11 can form a tight fit, enhancing the clamping and cutting effects.

[0025] At the front ends of both the main piece 2 and the secondary piece 1 are provided with pointed electrodes 10. The butting of the tips of the two pieces has the effect of bipolar electrocoagulation, which can facilitate hemostasis of small blood vessel bleeding in the anterior tracheal wall and the anterior fascia. The length of the electrode 10 is 3 mm.

[0026] The handle includes a main handle 7 and a secondary handle 4. The lengths of the two handles are 110 - 150 mm. The main handle 7 is connected to the secondary piece 1 of the tool head, and the secondary handle 4 is connected to the main piece 2 of the tool head. Main grips 8 and secondary grips 5 (both can be folded) are respectively installed on the main handle 7 and the secondary handle 4, facilitating the holding of the tool during the operation.

[0027] A transducer is installed inside the main handle 7. The transducer is connected to the connecting wire 6, and the other end of the connecting wire 6 is connected to the main unit. The main unit can provide electrical energy for the ultrasonic scalpel. The main unit can be battery-driven, with its volume reduced to half the size of a conventional main unit, enabling the operation to last for 30 - 60 minutes. However, it can be compatible with a general ultrasonic scalpel main unit when used for an extremely long time.

[0028] The transducer can convert electrical signals into mechanical vibrations. For the ultrasonic scalpel of the present invention, when the amplitude is set to 110 ± 10 μm, the blade-like structure 9 at the lower edge of the main blade 2 can be used for skin incision, without smoke and with little thermal damage; when the amplitude is set to 110 ± 10 μm, the blade-like structure 9 at the lower edge of the main blade 2 can effectively cut cartilage.

[0029] The portable ultrasonic scalpel for rapid bloodless tracheotomy of the present invention has three functions simultaneously: knife, scissors, and bipolar electrocoagulation, which can be freely switched according to needs to achieve the effect of rapid cutting and thorough hemostasis with one scalpel. When the output amplitude of the transducer is 110 ± 10 μm, the blade-like structure at the lower edge of the main blade can cut the skin; when the output amplitude of the transducer is 110 ± 10 μm, the blade-like structure at the lower edge of the main blade can effectively cut cartilage, such as for relatively superficial tracheotomy. When it is necessary to clamp blood vessels or cut soft tissues, the tool can be flipped and the joint surface between the main blade and the auxiliary blade can be used for operation to function as scissors. When it is necessary to stop bleeding of small blood vessels at the cutting position, the electrode at the front tip of the tool head can be used as a bipolar electrocoagulator to perform hemostasis operations in a timely manner.

[0030] The portable ultrasonic scalpel for rapid bloodless tracheotomy of the present invention is relatively short, especially the tool head is shorter, making it flexible for doctors to operate during the operation, not blocking the vision, effectively avoiding damage, and saving operation time; at the same time, it is also relatively portable, convenient to carry and cooperate with different devices for use.

[0031] Although the present invention has been described in detail with general descriptions and specific embodiments above, based on the present invention, some modifications or improvements can be made, which are obvious to those skilled in the art. Therefore, these modifications or improvements made without departing from the spirit of the present invention all fall within the scope of protection required by the present invention.
