Description

Technical Field

[0001] The utility model relates to the technical field of orthopedic instruments, and particularly relates to a non-inverting funnel chest combined orthopedic appliance. Background Art

[0002] The Nuss operation is a minimally invasive Nuss operation for treating pectus excavatum (PECTUS EXCAVATUM, PE) announced by American doctor Nuss in 1998. Pectus excavatum (PECTUS EXCAVATUM, PE) is a funnel-like deformity formed by the inward depression of the middle and lower segments of the sternum and adjacent costal cartilages. Its main feature is that the lower edge of the manubrium sterni to the upper edge of the xiphoid process of the sternal body inclines and depresses dorsally, and the corresponding costal cartilages on both sides also bend dorsally at the same time, making the lower part of the anterior chest wall funnel-shaped. The deepest point of the depression is usually at the junction of the lower end of the sternal body and the xiphoid process. In the Nuss operation, under the guidance of a thoracoscope, a Nuss orthopedic plate is inserted into the chest cavity for support. The sunken sternum is lifted up, and the deformed costal cartilages on both sides are pushed outwards together. The two ends of the Nuss orthopedic plate are fixed on both sides by a fixing cross bar with two holes, and the fixing device is wound and fixed with rib wires to support the sunken sternum, so as to achieve the purpose of chest wall orthopedics.

[0003] In the prior art, the common Nuss orthopedic plates include the early orthopedic plates and the non-inverting ones. Among them, for the early orthopedic plates, their main body parts are usually long strip-shaped metal plates of different specifications and sizes, and the specifications are selected and bent according to the target shape of orthopedics before the operation. Since the chest cavity of patients with pectus excavatum is sunken, while the ideal chest shape is upwardly raised with a certain curved surface. Therefore, after being bent into a predetermined shape, during the operation, an incision needs to be made in the patient's chest cavity, and then the orthopedic plate with an arc downward along the sunken trajectory is buried, and then it is flipped in the patient's chest cavity to turn the bending direction of the orthopedic plate upward to achieve the support process. This flipping action has a large degree of flipping, which is likely to cause greater damage to the chest wall tissue and requires a relatively high operation technique for doctors. In this regard, for the improved non-inverting orthopedic plate, through the improvement of the method, doctors can directly insert it along the incision during the operation and complete the shaping process from the concave trajectory to the convex trajectory.

[0004] However, in the actual implementation process, the inventor found that although this type of orthopedic plate avoids the flipping process, it still needs to be pre-formed and is exactly in the reverse arc shape of the patient's pectus excavatum. During the surgical insertion process, doctors need to use a large amount of force to manually insert and shape it. Content of the Utility Model

[0047] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all of the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without making creative efforts belong to the scope of protection of the present utility model.

[0048] It should be noted that, without conflict, the embodiments in the present utility model and the features in the embodiments can be combined with each other.

[0049] Next, the present utility model will be further described in conjunction with the accompanying drawings and specific embodiments, but it is not limited to the present utility model.

[0050] The present utility model includes:

[0051] A non-inverted funnel chest combined orthopedic appliance, as Figure 1 shown, includes a chest-piercing long needle 1 and an orthopedic plate 2;

[0052] As Figure 2 and Figure 3 shown, the chest-piercing long needle 1 is flat and long and has a first preset curvature. A tip 11 is provided at the first end of the chest-piercing long needle 1, and a connecting screw hole 12 is provided at the second end of the chest-piercing long needle 1;

[0053] As Figure 4 and Figure 5 shown, the orthopedic plate 2 is strip-shaped and has a second preset curvature. A connecting fixing hole 21 is provided at the first end of the orthopedic plate 2;

[0054] The connecting screw hole 12 and the connecting fixing hole 21 are matched, and a connecting device respectively penetrates into the connecting screw hole 12 and the connecting fixing hole 21 to connect the chest-piercing long needle 1 and the orthopedic plate 2;

[0055] The orthopedic plate 2 is made of memory metal.

[0056] Specifically, aiming at the problem that the non-inverted orthopedic plate in the prior art is relatively difficult to penetrate, this solution provides a combined appliance. By burying a chest-piercing long needle with a curvature before inserting the orthopedic plate, and then driving the orthopedic plate into the patient's body through the chest-piercing long needle. Since the orthopedic plate is made of memory metal, it can be pre-shaped and its hardness can be adjusted by cooling, and it can be more conveniently inserted into the patient's chest cavity, avoiding the problem of difficult penetration in the prior art.

[0057] Specifically, as Figure 1 shown, the chest-piercing long needle 1 is strip-shaped. The hyperbola shown in the figure is the omitted length, and the omitted part has no specific technical features. Figures 2 to 4 The hyperbola in

[0058] also has the same meaning. A tip 11 is provided at the first end of the chest-piercing long needle 1, which is in the shape of a flat duck beak, and its width and thickness gradually expand to facilitate penetration along the incision and cut and penetrate the muscle tissue. A connecting screw hole 12 is provided at the second end of the chest-piercing long needle 1 for subsequent connection with the orthopedic plate 2.

[0059] For example, in one embodiment, as Figure 6As shown, the non-inverting funnel chest combined orthopedic appliance further includes an auxiliary handle 3. The auxiliary handle 3 is generally in the shape of a flat-jawed pliers. A fixing post 31 is provided at the clamping part of the pliers head. The fixing post 31 can penetrate into the second end of the chest-piercing long needle 1 where a connecting screw hole 12 is provided, and effectively clamp the chest-piercing long needle 1 in cooperation with the anti-slip lines at the clamping part, facilitating the doctor to exert force to pierce the chest-piercing long needle 1 into the chest cavity. The shaded part shown in the figure represents the cross-section plane.

[0060] After passing through the chest cavity and reaching the other side incision, match the connecting screw hole 12 and the connecting fixing hole 21, and respectively penetrate the connecting device into the connecting screw hole 12 and the connecting fixing hole 21 to connect the chest-piercing long needle 1 and the orthopedic plate 2. Then the doctor can pull the chest-piercing long needle 1 from the other side to make the orthopedic plate 2 penetrate into the chest cavity to the predetermined position.

[0061] Among them, the orthopedic plate 2 is made of a shape memory metal, such as nickel-titanium alloy. The hardness of this type of alloy will decrease at low temperatures and the hardness and shape will recover at another higher temperature node. Based on this characteristic, an orthopedic plate 2 with a certain shape will be pre-made before the operation, so that it has a second preset curvature conforming to the ideal orthopedic contour. During the operation, cool down the orthopedic plate 2 to reduce its hardness, and shape it into the same curvature as the chest-piercing long needle or a curvature shape convenient for passing through the chest wall. After passing through the chest-piercing long needle, then connect the chest-piercing long needle 1 and the orthopedic plate 2 and pull the orthopedic plate into the chest cavity. Since the shape of the orthopedic plate 2 is similar to that of the chest-piercing long needle or is adjusted to a suitable shape, it can smoothly enter the chest cavity along the collapsed contour of the funnel chest. Subsequently, circulate and heat the normal saline in the endoscope circulating heating pipeline in the chest cavity to make the orthopedic plate 2 recover its hardness and the pre-made shape to complete the propping.

[0062] In the above process, since the chest-piercing long needle 1 has a first preset curvature conforming to the collapsed shape and a relatively high hardness, it can be more conveniently pierced into the chest cavity, avoiding the inconvenience in the piercing process of the non-inverting orthopedic plate in the prior art. At the same time, by preparing the orthopedic plate 2 with a shape memory metal, it can be supported after smoothly penetrating into the chest cavity, avoiding the problems of difficult penetration or damage to the chest cavity.

[0063] In one embodiment, the non-inverting funnel chest combined orthopedic appliance further includes an endoscope.

[0064] The endoscope includes a main pipeline and a circulation channel arranged around the main pipeline. Normal saline with a preset temperature is introduced into the circulation channel.

[0065] Specifically, during the process of inserting the trans-thoracic long needle 1 and implanting the orthopedic plate 2, it is often necessary to observe the situation inside the thoracic cavity through an endoscope and guide the insertion process. At the same time, due to the material characteristics of the orthopedic plate 2, it needs to be heated to restore its shape. In this embodiment, a circulation channel is also provided beside the improved endoscope around the main pipeline, and physiological saline with a preset temperature can be introduced into the circulation channel. Specifically, taking a fiber optic endoscope as an example, its main pipeline includes an observation fiber tube, etc. A circulation channel is additionally provided inside the main pipeline, and the circulation channel is connected to an external circulation device, such as a combination of a circulation pump and a heating and constant temperature device. Physiological saline at a certain temperature is introduced into the circulation channel to maintain the temperature increase inside the thoracic cavity, facilitating the orthopedic plate 2 to restore its shape.

[0066] In one embodiment, as Figure 2 , Figure 3 shown, the second end of the trans-thoracic long needle 1 includes a first sinking structure 13, and the thickness of the first sinking structure 13 in the cross-section is less than the thickness of the first main body part of the trans-thoracic long needle 1;

[0067] The connecting screw hole 12 is arranged on the first sinking structure 13;

[0068] As Figure 4 , Figure 5 shown, the first end of the orthopedic plate 2 is provided with a second sinking structure 22, and the thickness of the second sinking structure 22 in the cross-section is less than the thickness of the second main body part of the orthopedic plate 2;

[0069] The connecting fixing hole 21 is arranged on the second sinking structure 22.

[0070] Specifically, to achieve a better insertion process, in this embodiment, the connection part between the trans-thoracic long needle 1 and the orthopedic plate 2 is also improved. Mainly, stepped first sinking structure 13 and second sinking structure 22 are respectively processed at the endpoints of the trans-thoracic long needle 1 and the orthopedic plate 2, and they are thinned relative to their respective main body parts. When connecting the connecting screw hole 12 and the connecting fixing hole 21, the combined thickness of the thinned first sinking structure 13 and second sinking structure 22 is close to or slightly thinner than the thickness of the main body structure, avoiding the problems of damage to the thoracic cavity caused by excessive thickness at the joint and inconvenient insertion.

[0071] Furthermore, a docking notch 14 is arranged at the end of the first sinking structure 13;

[0072] A docking protrusion 23 matching the docking notch is arranged on the cross-section of the second main body part close to the second sinking structure 22.

[0073] In addition, to achieve a better connection effect between the trans-thoracic long needle 1 and the orthopedic plate 2 and avoid problems such as jamming or damage to the thoracic cavity caused by the rotation of the connection part around the bolt during the pulling process of the trans-thoracic long needle 1 and the orthopedic plate 2, in this embodiment, a docking notch 14 is also introduced at the end of the first sinking structure 13 and a docking protrusion 23 is introduced above the second sinking structure 22. The docking notch 14 and the docking protrusion 23 are matching structures. For example, in one embodiment, the docking notch 14 is a right-angled triangle notch and the docking protrusion 23 is a right-angled triangle protrusion. The docking notch 14 and the docking protrusion 23 are abutted against each other to fix the sides of the trans-thoracic long needle 1 and the orthopedic plate 2 and prevent rotation.

[0074] Similarly, as Figure 7 shown, a docking protrusion 32 can also be provided on the auxiliary handle 3 to achieve a better fixing effect during the insertion process.

[0075] Specifically, the auxiliary handle 3 is generally in the shape of a flat-nose pliers. A protruding fixed end point is provided at the clamping part of the pliers head. The protruding fixed end point can penetrate into the connection screw hole 12 provided at the second end of the trans-thoracic long needle 1. At this time, a corresponding docking protrusion 32 is provided on one end surface of the protrusion corresponding to the docking notch 14, and the cross-section of the pliers head is processed into a shape corresponding to the stepped shape of the first sinking structure 13.

[0076] During the clamping process, the second end of the trans-thoracic long needle 1 is sent into the pliers head part, and the connection screw hole 12 is sleeved on the fixing column 31 of the auxiliary handle 3. At this time, the docking notch 14 abuts against the docking protrusion 31, and then the pliers head is closed. The handle is locked by the locking device 33 at the tail of the auxiliary handle 3 to prevent the pliers head from loosening when exerting force.

[0077] During the process of penetrating into the thoracic cavity, since the docking notch 14 abuts against the docking protrusion 32, the degree of freedom of the trans-thoracic long needle 1 in the plane is restricted, and the problem of the trans-thoracic long needle 1 rotating and causing harm to the patient during the force application process can be avoided.

[0078] Furthermore, as Figure 8 shown, the auxiliary handle 3 further includes an orthopedic plate clamp that can be used to clamp the orthopedic plate 2. The orthopedic plate clamp is used to push the orthopedic plate 2 from the tail during the process of withdrawing the trans-thoracic long needle 1 and inserting the orthopedic plate 2. The main difference between this orthopedic plate clamp and the usual auxiliary handle 3 is that a docking notch 34 is provided at the pliers head part, which is used to match the docking protrusion 23 at the tail of the orthopedic plate 2.

[0079] In one embodiment, a third sinking structure 24 is provided at the second end of the orthopedic plate 2, and the shape of the third sinking structure 24 matches that of the second sinking structure 22;

[0080] The second main body part is provided with a docking protrusion 23 on the cross-section close to the third sinking structure 24;

[0081] As Figure 9 shown, the non-inverted funnel chest combined orthopedic appliance further includes a pair of fixing plates 4, and the fixing plates 4 are in the shape of rectangular sheets;

[0082] As Figure 10 、 Figure 11 shown, a docking groove 41 is provided in the central part of the fixing plate 4 in the direction of the short axis, the thickness of the docking groove 41 is smaller than the thicknesses of both ends of the fixing plate, a docking notch 42 is provided on the side of the docking groove 41, and a docking hole 43 is provided in the docking groove 41;

[0083] Fixing screw holes 44 are provided at both ends of the fixing plate.

[0084] Specifically, in order to enable the orthopedic plate 2 to be effectively connected to the sternum, in this embodiment, a third sinking structure 24 is further provided at the second end of the orthopedic plate 2, and the shape of the third sinking structure 24 matches that of the second sinking structure 22; a docking protrusion 23 is provided on the cross-section of the second main body part close to the third sinking structure 24, so that the left and right sides of the orthopedic plate 2 respectively have the same interfaces.

[0085] Then, a fixing plate 4 is designed for connecting to the sternum. Among them, the fixing plate 4 is made of medical stainless steel material. After passing through the orthopedic plate 2, the docking hole 43 and the connection fixing hole 21 are connected by bolts, so that the fixing plate 4 can be installed at the end point of the orthopedic plate 2, and the docking notch 42 abuts against the docking protrusion 23 to prevent rotation.

[0086] Fixing screw holes 44 are provided at both ends of the fixing plate 4 for connecting and fixing to the sternum.

[0087] By repeating the above installation process to realize the fixing process of both ends of the orthopedic plate 2. At the same time, due to the presence of the thinned docking groove 41, when the docking groove 41 coincides with the second and third sinking structures, the joint position will not be too thick.

[0088] In one embodiment, as Figure 12 shown, the axis of the docking groove 41 is set at a preset angle relative to the long axis of the fixing plate 4.

[0089] Specifically, in order to realize the fixation of the sternum of patients with different shapes, in this embodiment, the direction of the docking groove 41 is further adjusted so that it can be set at a preset angle relative to the long axis of the fixing plate 4, such as perpendicular or a certain inclination angle, etc., increasing the applicable range of the appliance.

[0090] In addition, the tip 11 is in the shape of an isosceles trapezoid in the top view direction, and the width of the end point of the tip 11 is smaller than the width of the main body of the chest-piercing long needle 1;

[0091] Two upper vertex angles of the isosceles trapezoid are processed with chamfers.

[0092] The tip 11 is in the shape of a round-headed cone in the front view direction.

[0093] Chamfers are processed around the chest-piercing long needle 1 and the orthopedic plate 2 to avoid damaging the thoracic cavity.

[0094] On the second main body part of the orthopedic plate 2, multiple pairs of circular teeth are also processed along the short-axis direction for auxiliary fixation by binding the patient's ribs with materials such as steel wires.

[0095] With the above settings, the following method can be adopted for installation during use, for example:

[0096] 1. According to the distortion condition of the PE patient, select the chest-piercing long needle 1 with the corresponding depression curvature, and clean and disinfect it together with other combined instruments. Clamp and fix the chest-piercing long needle 1 with the disinfected auxiliary handle 3.

[0097] 2. According to the normal surgical requirements, disinfect and make incisions on both sides of the patient's chest. Hold the auxiliary handle 3 and insert the chest-piercing long needle 1 into the patient's chest wall. At the same time, insert the endoscope through the auxiliary incision to observe the running state of the chest-piercing long needle 1 until the chest-piercing long needle 1 exits through the incision at the other end of the thoracic cavity.

[0098] 3. Remove the auxiliary handle 3. After shaping the orthopedic plate 2 to the predetermined correction shape in the refrigerant, connect it to the tail of the chest-piercing long needle 1. It can be fixedly connected with a connecting auxiliary screw, or can also be connected with various disinfected medical ropes. Then install the auxiliary handle 3 at the rear end of the orthopedic plate 2.

[0099] The above is to connect the orthopedic plate 2 after inserting the chest-piercing long needle 1 to ensure that the orthopedic plate will not restore its shape and harden due to the temperature rise during the slow chest-piercing process.

[0100] 4. Pull the chest-piercing long needle 1 to drive the orthopedic plate 2, and at the same time push the handle end. Under the combined action, pull out the chest-piercing long needle 1, and the orthopedic plate 2 appears on the other side. At this time, the orthopedic plate 2 is already in the position where it needs to be implanted in the thoracic cavity.

[0101] 5. Remove the chest-piercing long needle 1 at the end where the orthopedic plate 2 exits. According to the inclination angle between the orthopedic plate 2 and the ribs, select the disinfected fixing plate 4 with a suitable angle and fix it to the orthopedic plate with screws, and fix it to the ribs with stainless steel wires through 2 fixing holes (selected according to the surgical situation). At the other end (confirmed according to the exposed length in the design), the auxiliary handle 3 can be removed or retained.

[0102] 6. Inject physiological saline and warm water (within the temperature range that can keep the water temperature from scalding biological tissues and can restore the orthopedic plate to the designed convex state) through the circulation channel of the endoscope. The orthopedic plate starts to heat up. Slowly move the endoscope back while pulling it, so that the entire orthopedic plate 2 restores its shape to the designed convex state. When it is completely pulled out, if it is felt that the force for restoring deformation is insufficient during the process, the "handle" can be used to apply additional force at one or both ends to assist the orthopedic plate 2 in supporting the rib to reach the designed convex position.

[0103] 6. Remove the auxiliary handle 3. Depending on the situation, fix a fixing plate or not at the end without adding the fixing plate 4.

[0104] 7. Suture and dress according to the normal requirements of the operation.

[0105] The above is only a preferred embodiment of the present utility model, and does not limit the implementation mode and protection scope of the present utility model. For those skilled in the art, it should be realized that all equivalent replacements and obvious changes made by using the description and illustrations of the present utility model should be included in the protection scope of the present utility model.
