Abstract
Description
Technical Field
[0001] The invention relates to a surgical auxiliary tool, in particular to a luminous guide core adapted to a surgical pipe. Background Art
[0002] Patients who have just completed surgery and are unable to eat independently, or unconscious patients, all need to have a nasogastric tube or a transnasal gastric tube inserted. However, in existing clinical practice, during surgery with the chest opened, the physician can intuitively determine the direction of the tube by feel, thereby completing the insertion of the tube so that the gastric tube section is located exactly in the stomach for supply, and the intestinal tube is located exactly in the intestine for supply.
[0003] However, considering the postoperative healing speed and the infection risk of open surgery, current clinical surgery tends to adopt minimally invasive surgery. However, when minimally invasive surgery requires catheterization, the process of catheterization becomes very difficult. Since the window of minimally invasive surgery is extremely small, intestinal intubation needs to be Figure 1 As shown, the target position can be reached only by continuously passing through the cardia and pylorus. Some double-tube intubation operations also require that the gastric tube section be located exactly between the cardia and pylorus (the outlet of the nutrient solution is close to the pylorus). Therefore, whether it is a double tube or a single tube, it is difficult to accurately place the tube through the two gates if the physician cannot determine the direction of the tube by observation or touch. Taking the more complex double-tube intubation as an example, in a minimally invasive state, the physician cannot determine the direction of the intestinal tube section (especially the liquid outflow position of the intestinal tube) and the position of the hole by touch, and whether the gastric tube section has reached the appropriate position between the cardia and pylorus. Therefore, the process of placing the tube often tests the physician's personal experience and ability, and thus wastes a lot of surgical time and increases the difficulty of the operation.

[0062] The present invention is capable of various modifications and various embodiments, and therefore specific embodiments are illustrated and described in the accompanying drawings. However, this is not intended to limit the present invention to specific implementations, but should be understood to include all modifications, equivalents, and even substitutes that fall within the concept and technical scope of the present invention.
[0063] like Figure 1 As shown, the light-emitting guide core adapted for the surgical tube 10 provided in this embodiment comprises a light-emitting guide core body 100 and a guide core seat 200;
[0064] like Figure 2 As shown, the light-emitting core body is a curlable and cuttable structure, which includes an optical fiber 110 and an optical fiber sheath layer 120 wrapped around the optical fiber;
[0065] The optical fiber sheath layer is made of elastic medical rubber. The elastic surface protects the optical fiber while improving its bendability.
[0066] In another test example, the optical fiber sheath layer is made of metal materials such as stainless steel, nickel-titanium alloy or high-tensile stainless steel. The metal sheath not only protects the optical fiber and is bendable, but also provides a certain rigidity, thereby achieving a role similar to that of a guide wire.
[0067] In another test example, Figure 3 As shown, the optical fiber sheath layer 120 includes an inner sheath layer 121 and an outer sheath layer 122;
[0068] The inner sheath layer 121 is made of elastic material;
[0069] The outer jacket layer 122 is made of a metal material, thereby improving toughness and achieving rigidity.
[0070] In other experimental examples, the light-emitting core body has more than one light-emitting point, and the arrangement of the light-emitting points can be determined according to the basic configuration of the gastrointestinal cannula itself. For example, based on the distance from the tip of the traditional cannula to the liquid outlet is about 1 cm, two light-emitting positions are set at the tip and the liquid outlet respectively.
[0071] The realization of multiple light-emitting positions can be achieved by providing a transparent material at the corresponding position of the sheath layer or directly partially peeling off the sheath at the position to expose the optical fiber.
[0072] like Figure 1 As shown, the core guide seat 200 includes a core guide mounting portion 210 and a light source emitting portion 220;
[0073] The guide core mounting portion 210 is a channel 211 that matches the light guide core body, that is, during use, such as Figure 7 As shown, the light-emitting core body 100 can be fixed by inserting it into the channel. Generally speaking, the inner surface is preferably made of silicone rubber or similar materials, so as to increase the adhesion between the materials and prevent the core body from slipping out.
[0074] In a test case, Figure 4 As shown, the inner surface of the channel of the matching light-emitting guide core body has a wavy resistance-increasing pattern 2111, thereby further preventing the guide core body from slipping by increasing resistance.
[0075] In another test example, Figure 5 As shown, the outer surface of the light-emitting core body is partially or entirely provided with resistance-increasing lines 2001. Generally speaking, if the light-emitting core body is of a fixed length, only the head end, that is, the end that matches the channel, is provided with lines. However, considering that the light-emitting core body can be a rolled product with no fixed length, it can be cut as needed during use. Therefore, in this design, it is preferred to use a solution in which the entire length is provided with lines, so that the anti-slip effect can be achieved regardless of which section is the starting end.
[0076] Of course, in order to improve the anti-slip effect, you can use Figure 4 Channel, with Figure 5 The guide core body achieves a more stable mutual fixation result through the relative textures of each other.
[0077] In another test example, an external hoop is used to achieve mutual restraint between the guide core mounting portion and the guide core. Figure 8 As shown, the head end of the core guide seat is a structure with a retractable inner diameter, and the channel can be scaled based on the retractable inner diameter of the head end of the core guide seat. The specific structure is: the head end 201 of the core guide seat is composed of an elastic multi-piece structure 2011, which and the main body of the core guide seat are in the shape of a bullet head that bends inwards;
[0078] The center of the elastic multi-piece structure 2011 is a channel 211 matching the light-emitting core body;
[0079] Also includes a screw-tightening hoop 300;
[0080] The head 301 of the screw-tightening sleeve 300 is bent inward, and the tail 302 has an internal thread;
[0081] The main body 202 of the core guide seat 200 has an external thread 2021 at one end connected to the head end 201 of the core guide seat;
[0082] The internal thread matches the external thread in the manner shown by the arrow. During the process of mutual engagement and tightening, the screw tightening sleeve moves in the direction of the main part of the guide core seat, and its head gradually tightens the elastic multi-piece structure. During the process of reverse unscrewing, the screw tightening sleeve moves in the opposite direction of the main part of the guide core seat, and the elastic multi-piece structure is loosened.
[0083] like Figure 1 As shown, the end of the channel 211 is directly opposite to the light source emitting end of the light source emitting part, so that the laser from the emitting end can directly enter the channel.
[0084] In an experimental example, the light source is multi-colored, which is used to express different length intervals or different feature representations (such as: top, liquid outlet, or different intestinal / gastric tube segments). In this case, generally speaking, there are multiple optical fibers and corresponding light sources, that is, different optical fibers correspond to different emitting ends.
[0085] In another experimental example, the position where the end of the channel intersects with the light source emission end may have a focusing structure 230, and the focusing structure may be a focusing lens or a prism (such as Figure 7 ) shape, that is, to direct all the light to the end of the channel.
[0086] like Figure 7 As shown, the head end 201 of the core guide seat has a structure that matches the input end 11 of the surgical pipeline 10, that is, the input end of the general surgical pipeline is installed with a similar cone-shaped joint 11 based on the needs of infusion or subsequent interventional treatment. The head end 201 of the core guide seat of this embodiment also has a cone-shaped structure, so that it can be inserted into the joint to achieve docking (specific applications such as Fig.12 shown).
[0087] In one test example, the outer surface of the head end 201 of the guide core seat has a resistance-increasing pattern, that is, similar to Figure 4 and Figure 5 The shape of the rough surface;
[0088] In another test example, Figure 6 As shown, the outer surface of the head end 201 of the core guide seat has a limiting element 2012, which is an inverted C-shaped buckle edge, so that when it is connected to the input end 11 of the surgical tube 10, the edges are buckled to achieve mutual fixation.
[0089] In another test example, the head end 201 of the core guide seat and the input end 11 of the surgical tube 10 are screwed together through matching thread structures.
[0090] In another test example, Fig. 9As shown, the outer surface of the head end 201 of the guide core seat is a multi-level tower structure; similarly, the inner tube wall of the surgical pipeline input end 11 is a shape matching the multi-level tower structure, so as to achieve a mutual interlocking connection between the two. Since both materials are medical rubber materials with slight elasticity, when they are nested, they can achieve an adsorption connection with each other. The specific application state is as follows Fig.10 shown.
[0091] like Figure 10-12 As shown, during use, the guide core is cut according to the length of the cannula (the length is selected based on the actual in vivo environment of the patient), one end of the guide core is inserted from the head end of the guide core seat, and the other end is abutted against the tip of the cannula, and the head of the guide core seat is buried in the pipeline input end, thereby achieving the docking of the three, and the power is turned on through the power socket or mobile power supply, so that the guide core can directly emit light in the cannula. When the cannula with the guide core enters the stomach, the orientation of the tube body is indicated. The specific usage status diagram is as shown in Fig.13 shown.
[0092] Although the above description is centered on the embodiment, it is only an example and does not limit the present invention. It is clear to those skilled in the art that various modifications and applications not illustrated above can be made within the scope of the essential characteristics of the present embodiment. For example, each component specifically shown in the embodiment can be implemented after being modified. Moreover, various differences related to such modifications and applications should be interpreted as being included in the scope of the present invention as defined in the attached claims.
