Description

Technical Field

[0001] The invention relates to the technical field of esophageal probes, and in particular to an esophageal probe. Background Art

[0002] Congenital esophageal atresia is a serious congenital malformation, and long-segment esophageal atresia is a more serious type. Long-segment esophageal atresia refers to the proximal and distal ends of the esophagus being more than 2.5 cm apart, making primary anastomosis more difficult. Its treatment is still a challenge for pediatric surgeons.

[0003] The main treatment methods currently available include esophageal self-lengthening followed by anastomosis and esophageal replacement procedures, but it is generally believed that the method of using esophageal materials for anastomosis is more physiological and has better results. There are many ways to lengthen the esophagus itself, including waiting for the esophagus to grow naturally, lengthening the esophagus with tension (such as using a metal bougie), and lengthening the esophagus with external traction (such as the Foker procedure).

[0004] Metal bougies are widely used in clinical practice because they are easy to obtain and highly manipulable. When metal bougies are ineffective in lengthening the esophagus, Foker's procedure or esophageal replacement therapy should be considered.

[0005] The process of extending the esophagus with a metal probe is to insert the probe through the mouth or through the gastrostomy stoma and apply force longitudinally. Currently, there is a lack of esophageal bougies in clinical practice; sometimes a gallbladder probe is used as an alternative, but the head of the gallbladder probe is sharp and there is a risk of perforation when extending the esophagus. Summary of the invention

[0006] To this end, the present invention provides an esophageal probe to solve the above-mentioned problems in the prior art.

[0007] In order to achieve the above object, the present invention provides the following technical solutions:

[0008] An esophageal probe comprises a probe head, a bougie and a handle. The probe head is arranged at one end of the bougie and the handle is arranged at the other end of the bougie. The end of the probe head is a smooth curved surface structure without sharp edges and the edge of the probe head is smooth.

[0009] Furthermore: the probe head, the bougie and the handle are integrally manufactured from the same metal material.

[0010] Further: the bougie is bendable.

[0011] Furthermore: a pressure sensor is provided at the end of the probe head, and the pressure data indicator is connected to the pressure sensor via a data line.

[0012] Furthermore: the probe head and the bougie are connected by a threaded connection; the handle and the bougie are connected by a threaded connection.

[0013] Furthermore, a threaded hole is provided at one end of the probe head close to the bougie, and a stud is provided at one end of the bougie close to the probe head, and the stud and the threaded hole are used in coordination.

[0014] Furthermore: the probe head and the bougie are connected by a threaded connection; the handle and the bougie are connected by a threaded connection; an endoscope is provided inside the probe head, a glass sheet is provided on the outside of the end of the endoscope, and the glass sheet is fixed to the probe head by a pressing ring; a gasket is provided between the glass sheet and the probe head.

[0015] Furthermore: the pressure ring is connected to the probe head by means of a threaded connection.

[0016] Furthermore: the pressure ring includes a pressure ring, a threaded connection part and a slot, and the threaded connection part and the pressure ring are connected together; the pressure ring and the threaded connection part are made of the same material in one piece.

[0017] Further: the end surface of the pressure ring is provided with a plurality of grooves.

[0018] The present invention has the following advantages: the end surface of the probe head in the present invention that contacts the esophagus is smooth and not sharp, which can greatly reduce the risk of esophageal perforation;

[0019] The pressure sensor can visualize the force data applied to the esophageal probe when the esophagus is extended, so as to perform the surgery more accurately and further reduce the risks caused by excessive force.

[0020] The parts of the esophageal probe are connected in a detachable manner. When some parts are damaged, the damaged parts can be replaced in time, which can reduce the loss and expenditure of the equipment;

[0021] The use of an endoscope enables visualization during the operation of the esophageal probe, making the operation more precise. BRIEF DESCRIPTION OF THE DRAWINGS

[0035] like Figure 1 An esophageal probe comprises a probe head 1, a probe rod 2 and a handle 3. The probe head 1 is provided at one end of the probe rod 2, and the handle 3 is provided at the other end of the probe rod 2. The probe head 1, the probe rod 2 and the handle 3 are integrally made of the same metal material.

[0036] The end of the probe head 1 is a smooth curved structure without sharp edges, and the edges of the probe head 1 are smooth. In this embodiment, in order to achieve the best effect, the main body of the probe head 1 is an ellipsoid structure, and the end of the probe head 1 away from the bougie 2 is a spherical structure, and the spherical structure and the ellipsoid are smoothly connected.

[0037] The bougie 2 can be bent or straightened.

[0038] The end surface of the probe head 1 in the present invention that contacts the esophagus is smooth and not sharp, which can greatly reduce the risk of esophageal perforation.

[0039] like Fig. 9 , 10 As shown, the esophageal probe of the present invention has a probe head 1 with various specifications, and the size of the probe head 1 passing through the gastrostomy opening is smaller. Under the interaction of the two esophageal probes, the esophagus can be extended.

[0040] Embodiment 2

[0041] like Figure 2 As shown, an esophageal probe includes a probe 2, a pressure sensor 4 and a pressure data indicator 5. A probe head 1 is provided at one end of the probe 2, and a handle 3 is provided at the other end of the probe 2. The probe head 1, the probe 2 and the handle 3 are integrally made of the same metal material. The pressure sensor 4 is provided at the end of the probe head 1, and the pressure data indicator 5 is connected to the pressure sensor 4 through a data line.

[0042] The end of the probe head 1 is a smooth curved surface structure without sharp edges, and the edge of the probe head 1 is smooth.

[0043] In this embodiment, in order to achieve the best effect, the main body of the probe head 1 is an ellipsoid structure, the end of the probe head 1 away from the bougie 2 is a spherical structure, and the spherical structure and the ellipsoid are smoothly connected.

[0044] The bougie 2 can be bent or straightened.

[0045] In this embodiment, the pressure receptor 4 is a common pressure sensor.

The threaded connection part 802 and the pressure ring 803 are connected together, and the pressure ring 803 can contact the glass sheet 7. The pressure ring 803 and the threaded connection part 802 are made of the same material.

[0060] The end surface of the pressure ring 803 is provided with a plurality of slots 801 . In the present embodiment, four slots 801 are provided. The pressure ring 8 can be screwed onto the probe head 1 by inserting a special tool into the slots 801 and then rotating the tool.
